NJRC NJU7250 Low dropout voltage regulator Datasheet

NJU7250
Low Dropout Voltage Regulator
■ GENERAL DESCRIPTION
■ PACKAGE OUTLINE
The NJU7250 series is low dropout voltage and high
precision positive voltage regulator with ON/OFF control.
This IC is suitable for the battery items because of low
operating current and 150mA output current.
