NJU7771/72/73/74/75/76
LOW DROPOUT VOLTAGE REGULATOR
GENERAL DESCRIPTION
NJU7771/72/73/74/75/76 is a low dropout voltage regulator
designed for portable items.
Advanced CMOS technology achieves high ripple rejection
and low quiescent current.
NJU7774/75/76 features shunt switch which improves turn
off response of output voltage when ON/OFF control is used.
