S-1711 Series www.sii-ic.com SUPER-SMALL PACKAGE 2-CIRCUIT HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.3.0_00 (c) Seiko Instruments Inc., 2004-2010 The S-1711 Series is a 2-channel positive voltage regulator with a low dropout voltage, high output voltage accuracy, and low current consumption (150 mA output current) developed based on CMOS technology. A 1.0 F small ceramic capacitor can be used, and a 2-circuit voltage regulator with 1.0% high-accuracy output voltage is incorporated in an SOT-23-6 or super-small SNT-6A package. The A/ B/ E/ F types are provided with a discharge shunt function allowing high-speed output response when the ON/OFF pin is used. Compared with the conventional 150 mA output current 2-channel CMOS voltage regulators, high-density mounting is realized by using the super-small SNT-6A package and a small ceramic capacitor. Also, the low current consumption makes the S-1711 Series ideal for mobile devices. Features * Output voltage: * Low ESR capacitor can be used: * Wide input voltage range: * High-accuracy output voltage: * Low dropout voltage: * Low current consumption: 1.5 V to 5.5 V, selectable in 0.1 V steps.

Perform Application Conditions Input capacitor (CIN): Output capacitor (CL1, CL2): ESR of output capacitor: 1.0 F or more 1.0 F or more 1.0 or less Caution A general series regulator may oscillate, depending on the external components selected. Check that no oscillation occurs with the application using the above capacitor. Use input/output capacitor which has good temperature characteristics (conforming to the ceramic capacitor EIA X5R (JIS B) characteristics). Selection of Input and Output Capacitors (CIN, CL1, CL2) The S-1711 Series requires an output capacitor between the VOUT and VSS pins for phase compensation. Operation is stabilized by a ceramic capacitor with an output capacitance of 1.0 F or more in the entire temperature range. However, when using an OS capacitor, tantalum capacitor, or aluminum electrolytic capacitor, a ceramic capacitor with a capacitance of 1.0 F or more and an ESR of 1.0 or less is required. The value of the output overshoot or undershoot transient response varies depending on the value of the output capacitor. The required capacitance of the input capacitor differs depending on the application. The recommended value for an application is 1.0 F or more for CIN and 1.0 F or more for CL1 equaling CL2; however, when selecting the output capacitor, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual device. 20 Seiko Instruments Inc. SUPER-SMALL PACKAGE 2-CIRCUIT HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.3.0_00 S-1711 Series Explanation of Terms 1. Low dropout voltage regulator The low dropout voltage regulator is a voltage regulator whose dropout voltage is low due to its built-in low onresistance transistor. 2. Low ESR A capacitor whose ESR (Equivalent Series Resistance) is low. The S-1711 Series enables use of a low ESR capacitor, such as a ceramic capacitor, for the output-side capacitor CL1, CL2. A capacitor whose ESR is 1.0 or less can be used. 3. Output voltage (VOUT) The accuracy of the output voltage is ensured at 1.0% under the specified conditions of fixed input voltage*1, fixed output current, and fixed temperature. *1. Differs depending on the product. Caution If the above conditions change, the output voltage value may vary and exceed the accuracy range of the output voltage.

The error amplifier compares the reference voltage (Vref) with Vfb, which is the output voltage resistance-divided by feedback resistors Rs and Rf. It supplies the output transistor with the gate voltage necessary to ensure a certain output voltage free of any fluctuations of input voltage and temperature.

Output transistor The S-1711 Series uses a low on-resistance P-channel MOS FET as the output transistor. Be sure that VOUT does not exceed VIN + 0.3 V to prevent the voltage regulator from being damaged due to inverse current flowing from the VOUT pin through a parasitic diode to the VIN pin. Seiko Instruments Inc. 23 SUPER-SMALL PACKAGE 2-CIRCUIT HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR Rev.3.0_00 S-1711 Series 3. ON/OFF pins 1 and 2 These pins start and stop the regulator. When the ON/OFF pin is set to the shutdown level, the entire internal circuit stops operating, and the built-in Pchannel MOS FET output transistor between the VIN and VOUT pins is turned off, reducing current consumption significantly. Since the S-1711 Series A/ B/ E/ F types have a built-in discharge shunt circuit to discharge the output capacitance, the VOUT pin is forcibly set to VSS level. In the S-1711 Series C/ D/ G/ and H types, the VOUT pin is set to VSS level through several hundred k internal divided resistors between the VOUT and VSS pins. Note that the current consumption increases when a voltage of 0.3 V to VIN - 0.3 V is applied to the ON/OFF pin. The ON/OFF pin is configured as shown in Figures 24 and 25. In the S-1711 Series A/ C/ E/ G types, the ON/OFF pin is internally pulled up or pulled down to VSS when in the floating status, so the VOUT pin is set to the VSS level. In the S-1711 Series B/ D/ F/ H types, the ON/OFF pin is not internally pulled up or pulled down, so do not use these types with the ON/OFF pin in the floating status. When the ON/OFF pin is not used in the S-1711 Series B/ D/ F/ H types, connect the pin to the VIN pin in the B/ D types, and connect it to the VSS pin in the F/ H types.

Discharge shunt function (S-1711 Series A/ B/ E/ F types) The S-1711 Series A/ B/ E/ F types have built-in discharge shunt circuits to discharge the output capacitance. When the ON/OFF pin is set to shutdown level, turns the output transistor off, and turns the discharge shunt function on so that the output capacitor discharges. These types allow for the VOUT pin reach VSS level rapidly when compared with the S-1711 Series C/ D/ G/ H types that does not have discharge shunt circuits.

Pull-down/pull-up resistor (S-1711 Series A/ C/ E/ G types) In the S-1711 Series A/ C/ E/ G types, the ON/OFF pin is internally pulled up to VIN or pulled down to VSS, so the VOUT pin is in the VSS level when in the floating status. Note with caution that the power consumption of the IC is higher by that to be input to pull-up resistance or pull-down resistance the power off pin when the S-1711 Series A/ C types operated with the ON/OFF pin connected to VIN and the S-1711 Series E/ G types with the ON/OFF pin connected to VSS.

When mounting an output capacitor between the VOUT and VSS pins (CL1, CL2) and a capacitor for stabilizing the input between VIN and VSS pins (CIN), the distance from the capacitors to these pins should be as short as possible. * Note that the output voltage may increase when a series regulator is used at low load current (1.0 mA or less). * Note that the output voltage may increase due to driver leakage when a series regulator is used at high temperatures. * Generally a series regulator may cause oscillation, depending on the selection of external parts. The following conditions are recommended for this IC. However, be sure to perform sufficient evaluation under the actual usage conditions for selection, including evaluation of temperature characteristics. Input capacitor (CIN): Output capacitor (CL1, CL2): Equivalent series resistance (ESR): 1.0 F or more 1.0 F or more 1.0 or less Use input/output capacitor which has good temperature characteristics (conforming to the ceramic capacitor EIA X5R (JIS B) characteristics). * The voltage regulator may oscillate when the impedance of the power supply is high and the input capacitor is small or an input capacitor is not connected. * If the capacitance of the IC's output block is small, the power supply fluctuation and load fluctuation characteristics * * * * * 26 become worse. It is therefore important to sufficiently evaluate the output voltage fluctuation in the actual equipment. When the capacitance of the IC's output block is small, if the power supply suddenly increases sharply, a momentary overshoot may be output. It is therefore important to sufficiently evaluate the output voltage at power application in the actual equipment. The application conditions for the input voltage, output voltage, and load current should not exceed the package power dissipation. Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit. In determining the output current, attention should be paid to the output current value specified in Table 13 in the electrical characteristics and footnote *5) of the table.
