LP3878-ADJ Micropower 800mA Low Noise "Ceramic Stable" Adjustable Voltage
Regulator for 1V to 5V Applications
General Description
The LP3878-ADJ is an 800 mA adjustable output voltage
regulator designed to provide high performance and low noise in applications requiring output voltages as low as 1.0V. Using an optimized VIP™ (Vertically Integrated
PNP) process, the LP3878-ADJ delivers superior performance: Ground Pin Current: Typically 5.5 mA @ 800 mA load, and www.DataSheet4U.com 180 µA @ 100 µA load. Low Power Shutdown: The LP3878-ADJ draws less than 10 µA quiescent current when shutdown pin is pulled low. Precision Output: Guaranteed output voltage accuracy is 1% at room temperature. Low Noise: Broadband output noise is only 18 µV (typical) with 10 nF bypass capacitor.
