LP3993 Datasheet (National Semiconductor)

LP3993, 80mA Linear Regulator

The LP3993 is a linear regulator capable of supplying 80mA output current.

The LP3993 is designed to meet the requirements of digital systems where low IQ, fast start up, and good load transient response are important.

The device has been designed to work with small ceramic capacitors of 1.0µF and a
