NJU7741/44

LOW DROPOUT VOLTAGE REGULATOR

ꢀ GENERAL DISCRIPTION

ꢀ PACKAGE OUTLINE

NJU7741/44 is a low dropout voltage regulator with ON/OFF

control and Output shunt switch.

Advanced CMOS technology achieves high ripple rejection and

ultra low quiescent current.

It is suitable for reset small micro controller and other logic chips.

NJU7744 features shunt switch which improves turn off response

of output voltage when ON/OFF control is used.
