NJM12856U2

NJM12856 LDO with Reverse Current Protection / Soft Start / Discharge Function GENERAL DESCRIPTION The NJM12856 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 NJM12856U2 NJM12856DL3 FEATURE Operating Voltage Range 2.5V ~ 6.5V Output Voltage Accuracy VO 1.0% Output Current IO(min.)=1000mA 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 SOT-89-5, TO-252-5 PIN CONFIGRATION VOUT 1 GND 2 CS 3 5 VIN 2 GND 4 CONTROL NJM12856U2 5 CS 4 VOUT 3 3 GND 2 VIN 1 CONTROL NJM12856DL3 BLOCK DIAGRAM VIN CONTROL Reverse Current Protection Bandgap Reference Thermal Protection Over Current Protection VOUT CS GND Ver.2015-07-21 -1- NJM12856 OUTPUT VOLTAGE RANK LIST SOT-89-5 TO-252-5 Device Name NJM12856U2-15 NJM12856U2-18 Output Voltage 1.5V 1.8V Device Name NJM12856DL3-15 NJM12856DL3-18 NJM12856U2-25 2.5V NJM12856DL3-25 NJM12856U2-33 3.3V NJM12856DL3-33 NJM12856U2-05 5.0V NJM12856DL3-05 Output Voltage 1.5V 1.8V 2.5V 3.3V 5.0V ABS...
