NJU7780
NJU7780 is LOW DROPOUT VOLTAGE REGULATOR manufactured by New Japan Radio.
DESCRIPTION
The NJU7780/81 is a low dropout voltage regulator with ON/OFF
Control. Advanced CMOS technology achieves low quiescent current. It is suitable for battery operating applications. NJU7781 features shunt switch which improves turn off response of output voltage when ON/OFF control is used.
