NJRC NJU7231L25 High precision c-mos 3-terminal voltage regulator Datasheet

NJU7231
High Precision C-MOS 3-Terminal Voltage Regulator
■ GENERAL DESCRIPTION
■ 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.
