The foundation of any voltage reference is the band-gap circuit. While the reference in the LM4128 is developed
from the gate-source voltage of transistors in the IC, principles of the band-gap circuit are easily understood
using a bipolar example. For a detailed analysis of the bipolar band-gap circuit, see the AN-56 Application Report
(SNVA514).
SUPPLY AND ENABLE VOLTAGES
To ensure proper operation, VEN and VIN must be within a specified range. An acceptable range of input voltages
is
VIN > VREF + 400 mV (ILOAD ≤10 mA) (1)
The enable pin uses an internal pull-up current source (IPULL_UP ≊2 µA) that may be left floating or triggered by
an external source. If the part is not enabled by an external source, it may be connected to VIN. An acceptable
range of enable voltages is given by the enable transfer characteristics. See the Electrical Characteristics section
and Enable Transfer Characteristics figure for more detail. Note, the part will not operate correctly for VEN > VIN.
COMPONENT SELECTION
A small ceramic (X5R or X7R) capacitor on the input must be used to ensure stable operation. The value of CIN
must be sized according to the output capacitor value. The value of CIN must satisfy the relationship CIN ≥COUT.
When no output capacitor is used, CIN must have a minimum value of 0.1 µF. Noise on the power-supply input
may affect the output noise. Larger input capacitor values (typically 4.7 µF to 22 µF) may help reduce noise on
the output and significantly reduce overshoot during startup. Use of an additional optional bypass capacitor
between the input and ground may help further reduce noise on the output. With an input capacitor, the LM4128
will drive any combination of resistance and capacitance up to VREF/20 mA and 10 µF respectively.
The LM4128 is designed to operate with or without an output capacitor and is stable with capacitive loads up to
10 µF. Connecting a capacitor between the output and ground will significantly improve the load transient
response when switching from a light load to a heavy load. The output capacitor should not be made arbitrarily
large because it will effect the turn-on time as well as line and load transients.
While a variety of capacitor chemistry types may be used, it is typically advisable to use low esr ceramic
capacitors. Such capacitors provide a low impedance to high frequency signals, effectively bypassing them to
ground. Bypass capacitors should be mounted close to the part. Mounting bypass capacitors close to the part will
help reduce the parasitic trace components thereby improving performance.
SHORT CIRCUITED OUTPUT
The LM4128 features indefinite short circuit protection. This protection limits the output current to 75 mA when
the output is shorted to ground.
TURN ON TIME
Turn on time is defined as the time taken for the output voltage to rise to 90% of the preset value. The turn on
time depends on the load. The turn on time is typically 33.2 µs when driving a 1µF load and 78.8 µs when driving
a 10 µF load. Some users may experience an extended turn on time (up to 10 ms) under brown out conditions
and low temperatures (-40°C).
THERMAL HYSTERESIS
Thermal hysteresis is defined as the change in output voltage at 25ºC after some deviation from 25ºC. This is to
say that thermal hysteresis is the difference in output voltage between two points in a given temperature profile.
An illustrative temperature profile is shown in Figure 16.

This may be expressed analytically as the following:
where
• VHYS = Thermal hysteresis expressed in ppm
• VREF = Nominal preset output voltage
• VREF1 = VREF before temperature fluctuation
• VREF2 = VREF after temperature fluctuation (2)
The LM4128 features a low thermal hysteresis of 190 µV from -40°C to 125°C.
TEMPERATURE COEFFICIENT
Temperature drift is defined as the maximum deviation in output voltage over the operating temperature range.
This deviation over temperature may be illustrated as shown in Figure 17.

Temperature coefficient may be expressed analytically as the following:
where
• TD= Temperature drift
• VREF = Nominal preset output voltage
• VREF_MIN = Minimum output voltage over operating temperature range
• VREF_MAX = Maximum output voltage over operating temperature range
•ΔT = Operating temperature range (3)
The LM4128 features a low temperature drift of 75 ppm (max) to 100 ppm (max), depending on the grade, from -
40°C to 125°C.
LONG TERM STABILITY
Long-term stability refers to the fluctuation in output voltage over a long period of time (1000 hours). The LM4128
features a typical long-term stability of 50 ppm over 1000 hours. The measurements are made using 5 units of
each voltage option, at a nominal input voltage (5V), with no load, at room temperature.
EXPRESSION OF ELECTRICAL CHARACTERISTICS
Electrical characteristics are typically expressed in mV, ppm, or a percentage of the nominal value. Depending
on the application, one expression may be more useful than the other. To convert one quantity to the other one
may apply the following:
ppm to mV error in output voltage:
where
• VREF is in volts (V) and VERROR is in milli-volts (mV) (4)
Bit error (1 bit) to voltage error (mV):
where
• VREF is in volts (V)
• VERROR is in milli-volts (mV)
• and n is the number of bits (5)
mV to ppm error in output voltage:
where
• VREF is in volts (V)
• VERROR is in milli-volts (mV) (6)
Voltage error (mV) to percentage error (percent):
where
• VREF is in volts (V)
• VERROR is in milli-volts (mV) (7)

PRINTED CIRCUIT BOARD and LAYOUT CONSIDERATIONS
References in SOT packages are generally less prone to PC board mounting than devices in Small Outline
(SOIC) packages. To minimize the mechanical stress due to PC board mounting that can cause the output
voltage to shift from its initial value, mount the reference on a low flex area of the PC board, such as near the
edge or a corner.
The part may be isolated mechanically by cutting a U shape slot on the PCB for mounting the device. This
approach also provides some thermal isolation from the rest of the circuit.
Bypass capacitors must be mounted close to the part. Mounting bypass capacitors close to the part will reduce
the parasitic trace components thereby improving performance.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.

IMPORTANT NOTICE
Texas Instruments Incorporated (TI) reserves the right to make corrections, enhancements, improvements and other changes to its
semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers
should obtain the latest relevant information before placing orders and should verify that such information is current and complete.
TI’s published terms of sale for semiconductor products (http://www.ti.com/sc/docs/stdterms.htm) apply to the sale of packaged integrated
circuit products that TI has qualified and released to market. Additional terms may apply to the use or sale of other types of TI products and
services.
Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is
accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced
documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements
different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the
associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.
Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers
remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have
full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products
used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with
respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous
consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and
take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will
thoroughly test such applications and the functionality of such TI products as used in such applications.
TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,
including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to
assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any
way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource
solely for this purpose and subject to the terms of this Notice.
TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI
products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,
enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically
described in the published documentation for a particular TI Resource.
Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that
include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE
TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY
RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or
endorsement thereof. Use of TI Resources may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
TI RESOURCES ARE PROVIDED “AS IS” AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR
REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO
ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL
PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM,
INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF
PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL,
DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN
CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949
and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements.
Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such
products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards
and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must
ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in
life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.
Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life
support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all
medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.
TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).
Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications
and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory
requirements in connection with such selection.
Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s non-
compliance with the terms and provisions of this Notice.
