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
