NJU7747/48 LOW DROPOUT VOLTAGE REGULATOR GENERAL DISCRIPTION PACKAGE OUTLINE NJU7747/48 is a low dropout voltage regulator with ON/OFF control. Advanced CMOS technology achieves ultra low quiescent current. SC-82AB package and 0.1F small output capacitor make the NJU7747/48F4 NJU7747/48 suitable for space conscious applications. NJU7748 features shunt switch which improves turn off response of output voltage when ON/OFF control is used.
