NJU7790
LOW DROPOUT VOLTAGE REGULATOR
GENERAL DESCRIPTION
The NJU7790 is a 500mA output low dropout voltage
regulator with ON/OFF control.
Advanced CMOS technology achieves high ripple rejection
and low quiescent current.
Small packaging and 2.2µF small decoupling capacitor make the
NJU7790 suitable for space conscious applications.
