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.
