C-MOS 3-TERMINAL NEGATIVE VOLTAGE REGULATOR
■ GENERAL DESCRIPTION
The NJU7211 series is a C-MOS 3-terminal negative voltage
regulator which contains internal precision 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 NJU7211 series is suitable for battery operated items and
battery back-up systems because of low operating current and low
dropout voltage.
■ FEATURES
