  • 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.
