LP3879

LP3879 Micropower 800mA Low Noise "Ceramic Stable" Voltage Regulator for Low Voltage Applications June 2006 LP3879 Micropower 800mA Low Noise "Ceramic Stable" Voltage Regulator for Low Voltage Applications General Description 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 www.DataSheet4U.com 200 µA @ 100 µA load. Low Power Shutdown: The LP3879 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.
