LP3878 Datasheet Micropower 800ma Low Noise Ceramic Stable Voltage Regulator

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LP3878 Micropower 800mA Low Noise "Ceramic Stable" Voltage Regulator for Low Voltage Applications Designed for Use with Very Low ESR Output Capacitors November 2004 LP3878 Micropower 800mA Low Noise "Ceramic Stable".

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 www.DataSheet4U.com an external 10 nF capacitor to the bypass pin.

Using an optimized VIP™ (Vertically Integrated PNP) process, the LP3878 delivers superior performance: Ground Pin Current: Typically 5 mA @ 800 mA load, and 180 µA @ 100 µA load.

Key Features

  • n Standard output voltage: 1.00V n Custom voltages available from 1.0V to 1.2V (50 mV increments) n Input voltage: 2.2 to 6.0V n 1% initial output accuracy n Guaranteed 800 mA continuous output current n Designed for use with low ESR ceramic capacitors n Very low output noise with external capacitor n Sense option improves load regulation n 8 Lead LLP surface mount package n < 2.0 µA quiescent current in shutdown n Low ground pin current at all loads n High peak current capability (1200 mA typic.
