L88R05

·Features Minimum I/O voltage difference is small (0.5 V typ.), making power conservation possible, and makes smaller heatsink and
·transformers possible. . External capacitor for reset signal output delay time adjustment. Sink/source reset output provides compatibility with logic circuitry that has an internal pull-down resistor. Active pull-up
·facilitates noise suppression. . Various types of protective circuits on chip (fold back current limiting, thermal  rotection). The package is the TO220-5H; this package facilitates designs for the radiation of heat during the  ounting process.

·Prevents malfunction when the microcontroller power supply
·is turned on or off. Designed to handle malfunction caused by momentary power
·equipment, and other battery-powered equipment with little capacity to handle fluctuation in input voltage; also suited for equipment with large fluctuations in the primary power supply.

The L88R05 Series is a series of low-saturation voltage regulator ICs that are equipped with a function that generates a reset signal when the power supply for a microcontroller system is turned on or off.
