Low Dropout Voltage Regulator
GENERAL DESCRIPTION
■■■■
The NJU7250 series is low dropout voltage and high
precision positive voltage regulator with ON/O FF cont rol.
This IC is suitable for the battery items because of low
operating current and 150mA output cur r ent .
Furthermore, this series is packaged with MTP5
