NJM2881/82 LOW DROPOUT VOLTAGE REGULATOR GENERAL DESCRIPTION PACKAGE OUTLINE NJM2881/82 is a low dropout voltage regulator with ON/OFF control. Advanced Bipolar technology achieves low noise, high ripple rejection and low quiescent current. NJM2881/82F It is mounted on SOT-23-5 as small package and 1.0 F ceramic capacitor is available. Therefore it is suitable for cellular phone, camcorder, IC decoder, camera, and other portable items. FEATURES High Ripple Rejection 75dB typ. (f=1kHz ,Vo=3V version) Low Output Noise Voltage Vno=30 Vrms (Cp=0.01 F) Output capacitor with 1.0 F ceramic capacitor (Vo 2.7V) Output Current Io(max.)=300mA High Precision Output Vo 1.0% Low Dropout Voltage 0.10V typ.
