 GENERAL DESCRIPTION  PACKAGE OUTLINE

The NJU7777 is a 150mA output low dropout voltage

regulator with ON/OFF control.

Advanced CMOS technology achieves high ripple rejection

and low quiescent current.

Small packaging and 1µF small decoupling capacitor make the

NJU7777 suitable for space conscious applications.
