■ GENERAL DESCRIPTION

The NJU7222 series is a high precision output voltage (±2) and

high output current C-MOS 3-terminal positive voltage regulator

which contains internal accurate voltage reference, error amplifier,

control transistor, output voltage setting resistor and short current

protection circuit.

The regulation voltage is fixed by internal circuits and the following

line-up of different output voltage versions are available.

The short current protection circuit prevents destruction of a

element by careless great current output in short circuit.

The NJU7222 series is suitable for battery operated items and

battery back-up systems because of low operating current and low

dropout voltage.
