Description

General part information

LP3879 Series

The LP3879 is a 800 mA fixed-output voltage regulator designed to provide high performance and low noise in applications requiring output voltages between 1.0V and 1.2V.

Using an optimized VIP (Vertically Integrated PNP) process, the LP3879 delivers superior performance:

Ground Pin Current:Typically 5.5 mA @ 800 mA load, and 200 µA @ 100 µA load.
