NJU7222 Series PRELIMINARY HIGH PRECISION AND HIGH OUTPUT CURRENT C-MOS 3-TERMINAL VOLTAGE REGULATOR GENERAL DESCRIPTION PACKAGE OUTLINE 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. 3 2 The regulation voltage is fixed by internal circuits and the following 1 line-up of different output voltage versions are available. The short current protection circuit prevents destruction of a NJU7222U (SOT-89) 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.
