NJU7751/54
LOW DROPOUT VOLTAGE REGULATOR
GENERAL DISCRIPTION
NJU7751/54 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.
