LOW DROPOUT VOLTAGE
REGULATOR
GENERAL 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.
