NJU7231

High Precision C-MOS 3-Terminal Voltage Regulator

I GENERAL DESCRIPTION

I PACKAGE OUTLINE

The NJU7231 is high precision output voltage 3-terminal

positive voltage regulator.

The NJU7231 is suitable for battery operated items and

battery back-up systems, because of low operating current

and low dropout voltage.
