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 cellular phone application etc.
Advanced CMOS technology achieves high ripple rejection
and low quiescent current.
When the ON/OFF control is used, NJU7774/75/76 has high
transition response characteristics for shunt switch.
