NJU7747/48

LOW DROPOUT VOLTAGE REGULATOR

ꢀ GENERAL DISCRIPTION

NJU7747/48 is a low dropout voltage regulator with ON/OFF

control.

ꢀ PACKAGE OUTLINE

Advanced CMOS technology achieves ultra low quiescent current.

SC-82AB package and 0.1µF small output capacitor make the

NJU7747/48 suitable for space conscious applications.

NJU7747/48F4

NJU7748 features shunt switch which improves turn off response

of output voltage when ON/OFF control is used.
