NJU7211 Series C-MOS 3-TERMINAL NEGATIVE VOLTAGE REGULATOR GENERAL DESCRIPTION PACKAGE OUTLINE 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 3 line-up of different output voltage versions are available. 2 1 The NJU7211 series is suitable for battery operated items and battery back-up systems because of low operating current and low NJU7221U (SOT-89) dropout voltage.
