LP3878-ADJ  
Micropower 800mA Low Noise "Ceramic Stable"  
Adjustable Voltage Regulator for 1V to 5V Applications  
General Description  
Features  
n 1.0V to 5.5V output  
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.  
n Designed for use with low ESR ceramic capacitors  
n Very low output noise  
n 8 Lead PSOP and LLP surface mount package  
Using an optimized VIP (Vertically Integrated PNP) pro-  
<
n
10 µA quiescent current in shutdown  
cess, the LP3878-ADJ delivers superior performance:  
n Low ground pin current at all loads  
@
Ground Pin Current: Typically 5.5 mA 800 mA load, and  
n Over-temperature/over-current protection  
n -40˚C to +125˚C operating junction temperature range  
@
180 µA 100 µA load.  
Low Power Shutdown: The LP3878-ADJ draws less than  
10 µA quiescent current when shutdown pin is pulled low.  
Applications  
Precision Output: Guaranteed output voltage accuracy is  
1% at room temperature.  
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  
Low Noise: Broadband output noise is only 18 µV (typical)  
with 10 nF bypass capacitor.  
n Medical Instrumentation  
Basic Application Circuit  
20120903  
*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.
