NJU7780/81

LOW DROPOUT VOLTAGE REGULATOR

ꢀ GENERAL DESCRIPTION

The NJU7780/81 is a low dropout voltage regulator with ON/OFF

Control.

ꢀ PACKAGE OUTLINE

Advanced CMOS technology achieves low quiescent current.

It is suitable for cellular phone and other portable items.

When the ON/OFF control is used, NJU7781 has high transition

response characteristics for shunt switch.
