NJM12877 LDO with Reverse Current Protection / Soft Start / Discharge Function GENERAL DESCRIPTION The NJM12877 is a low dropout regulator which achieves high ripple rejection, low noise and high speed response with the bipolar technology. Adjustable soft-start function is useful for reducing inrush current and controlling power-on sequence. Moreover the discharge function makes effective sequence control with the soft-start function. In addition, the reverse current protection makes external .

NJM12877 LDO with Reverse Current Protection / Soft Start / Discharge Function GENERAL DESCRIPTION The NJM12877 is a low dropout regulator which achieves high ripple rejection, low noise and high speed response with the bipolar technology. Adjustable soft-start function is useful for reducing inrush current and controlling power-on sequence. Moreover the discharge function makes effective sequence control with the soft-start function. In addition, the reverse current protection makes external SBD unnecessary. ■ PACKAGE OUTLINE NJM12877KG1 NJM12877F FEATURES Operating Voltage Range 2.3V to 6.5V Output Voltage Accuracy VO 1.0% Output Current IO(min.)=200mA Reverse Current Protection Adjustable soft-start Function Discharge Function ON/OFF Control Correspond to Low ESR capacitor (MLCC) Thermal Shutdown Circuit Over Current Protection Circuit Package Outline DFN6-G1(ESON6-G1), SOT-23-5 PIN CONFIGRATION (Top View) (Bottom View) Cs 1 GND 2 CONTROL 3 6 VOUT 6 5 NC 5 4 VIN 4 NJM12877KG1 1 2 3 Exposed PAD on backside connected to GND.
