NJU7222 Series
HIGH PRECISION AND HIGH OUTPUT CURRENT
C-MOS 3-TERMINAL VOLTAGE REGULATOR
PRELIMINARY
■ 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.
