NJM12884
LDO with Reverse Current Protection / Soft Start / Discharge Function
GENERAL DESCRIPTION The NJM12884 is a low dropout
regulator which achieves high ripple rejection, low noise and high speed response with the bipolar technology. Adjustable soft-start function is useful for reducing inrush current and controlling power-on sequence. Moreover the discharge function makes effective sequence control with the soft-start function. In addition, the reverse current protection makes external SBD unnecessary.
