Description
The NJU7221 series is a high precision output voltage(±2%) 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 NJU7221 series is suitable for battery operated items and battery back-up systems because of low operating current and low dropout voltage.
