RP131x SERIES LOW ON RESISTANCE / LOW VOLTAGE 1A LDO NO.EA-174-111020 OUTLINE The RP131x Series are voltage-regulators with a built-in low ON-resistance transistor and output current is 1A capability. These ICs are capable of the low input voltage (Min.1.6V) and also the minimum output voltage can be set from 0.8V. (The output voltage is fixed in the IC.) Each of these ICs consists of a voltage reference unit, an error amplifier, a resistor net for setting output voltage, a chip enable circuit, current limit circuits for over-current and short, and a thermal-shutdown circuit. A standby mode with ultra low supply current can be realized with the chip enable function. The packages for these ICs are DFN1616-6B and DFN(PLP)1820-6 which are suitable for high density mounting of the ICs on boards. SOT-89-5, HSOP-6J and TO-252-5-P2 with high power dissipation are also available.

RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS) All of electronic equipment should be designed that the mounted semiconductor devices operate within the recommended operating conditions. The semiconductor devices cannot operate normally over the recommended operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And the semiconductor devices may receive serious damage when they continue to operate over the recommended operating conditions. 7 RP131x TYPICAL APPLICATION VDD C1 RP131x Series CE VOUT VOUT C2 GND Recommendation value of the external capacitors Capacitors VOUT VOUT 3.6V VOUT > 3.6V C1 C2 C1 C2 Kyocera 2.2F (size:1005) Kyocera 2.2F (size:1608) Kyocera 2.2F (size:1608) Kyocera 4.7F (size:1608) [CM05X5R225M06AB] [CM105X5R225K06AB] [CM105X5R225K06AB] [CM105X5R475M06AB] TECHNICAL NOTES When using these ICs, consider the following points: Phase Compensation In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, use a capacitor C2 with good frequency characteristics and ESR (Equivalent Series Resistance). If a tantalum capacitor is used, and its ESR of C2 is large, the loop oscillation may result. Because of this, select C2 carefully considering its frequency characteristics. PCB Layout Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result. Connect a capacitor C1 between VDD and GND pin with a capacitance value as "Recommendation value of the external capacitors" above or more, and as close as possible to the pins. Set external components, especially the output capacitor C2, as close as possible to the ICs, and make wiring as short as possible. 8 RP131x TEST CIRCUITS VDD VOUT RP131x Series C1 CE C2 V IOUT VOUT GND Basic Test Circuit VDD A ISS VOUT VOUT RP131x Series C1 CE C2 GND Test Circuit for Supply Current Pulse Generator VDD VOUT RP131x Series P.G.
