LP3879  
Micropower 800mA Low Noise "Ceramic Stable" Voltage  
Regulator for Low Voltage Applications  
General Description  
Features  
n Standard output voltage: 1.00V, 1.20V  
n Custom voltages available from 1.0V to 1.2V (50 mV  
increments)  
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.  
n Input voltage: 2.5 to 6V  
Using an optimized VIP (Vertically Integrated PNP) pro-  
n 1% initial output accuracy  
cess, the LP3879 delivers superior performance:  
n Designed for use with low ESR ceramic capacitors  
n Very low output noise  
@
Ground Pin Current: Typically 5.5 mA 800 mA load, and  
@
200 µA 100 µA load.  
n Sense option improves load regulation  
n 8 Lead PSOP and LLP surface mount packages  
Low Power Shutdown: The LP3879 draws less than 10 µA  
quiescent current when shutdown pin is pulled low.  
<
n
10 µA quiescent current in shutdown  
Precision Output: Guaranteed output voltage accuracy is  
1% at room temperature.  
n Low ground pin current at all loads  
n High peak current capability  
Low Noise: Broadband output noise is only 18 µV (typical)  
with 10 nF bypass capacitor.  
n Over-temperature/over-current protection  
n -40˚C to +125˚C junction temperature range  
Applications  
n ASIC Power Supplies In:  
- Desktops, Notebooks and Graphic Cards  
- Set Top Boxes, Printers and Copiers  
n DSP and FPGA Power Supplies  
n SMPS Post-Regulator  
n Medical Instrumentation  
Basic Application Circuit  
20161303  
*Capacitance values shown are minimum required to assure stability. Larger output capacitor provides improved dynamic response. Output capacitor must  
meet ESR requirements (see Application Information).  
**The Shutdown pin must be actively terminated (see Application Information). Tie to INPUT (Pin 4) if not used.
