NJU7202 Series
HIGH OUTPUT CURRENT C-MOS 3-TERMINAL VOLTAGE REGULATOR
■
GENERAL DESCRIPTION
The
NJU7202 series
is a 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
NJU7202 series
is suitable for battery operated items and
battery back-up systems because of low operating current and low
dropout voltage.
