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.
