NJU7222 Series

High Precision and High Output Current C-MOS 3-Terminal Voltage Regulator

Download Datasheet

Description

The NJU7222 series is a high precision output voltage (±2%) and 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 NJU7222 series is suitable for battery operated items and battery back-up systems because of low operating current and low dropout voltage.
