NJU7201 Series
C-MOS 3-TERMINAL POSITIVE VOLTAGE REGULATOR
■ GENERAL DESCRIPTION
The NJU7201 series is a C-MOS 3-terminal positive voltage
regulator which contains internal accurate voltage reference, error
amplifier, control transistor and output voltage setting resistor.
The regulation voltage is fixed by internal circuits and the following
line-up of different output voltage versions are available.
The NJU7201 series is suitable for battery operated items and
battery back-up systems because of low operating current and low
dropout voltage.
