LP3878

MICropower 800mA Low Noise "Ceramic Stable" Voltage

Regulator for Low Voltage Applications

Designed for Use with Very Low ESR Output Capacitors

General Description

The LP3878 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.

Output noise can be reduced to 18μV (typical) by connecting

an external 10 nF capacitor to the bypass pin.

Using an optimized VIP? (Vertically Integrated PNP) pro-

cess, the LP3878 delivers superior performance:

Ground Pin Current: Typically 5 mA @ 800 mA load, and

180 μA @ 100 μA load.

Sleep Mode: The LP3878 draws less than 2.0 μA quiescent

current when shutdown pin is pulLED low.

Precision Output: Guaranteed output voltage accuracy is

1% at room temperature.
