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