CS8121 5V/ 1A Linear Regulator with and ENABLE RESET

The CS8121 is a 5V, 1A precision linear regulator with two microprocessor compatible control functions and protection circuitry included on chip. The composite NPN-PNP output pass transistor assures a lower dropout voltage (1.2V @ 1A) without requiring excessive supply current (4mA). The CS8121Õs tw.
