LP3878-ADJ  
Micropower 800mA Low Noise "Ceramic Stable"  
Adjustable Voltage Regulator for 1V to 5V Applications  
General Description  
Features  
The LP3878-ADJ is an 800 mA adjustable output voltage reg-  
ulator designed to provide high performance and low noise in  
applications requiring output voltages as low as 1.0V.  
1.0V to 5.5V output  
Designed for use with low ESR ceramic capacitors  
Very low output noise  
Using an optimized VIP® (Vertically Integrated PNP) process,  
the LP3878-ADJ delivers superior performance:  
8 Lead PSOP and LLP surface mount package  
<10 μA quiescent current in shutdown  
Ground Pin Current: Typically 5.5 mA @ 800 mA load, and  
180 µA @ 100 µA load.  
Low ground pin current at all loads  
Over-temperature/over-current protection  
-40°C to +125°C operating junction temperature range  
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.  
Applications  
Low Noise: Broadband output noise is only 18 μV (typical)  
with 10 nF bypass capacitor.  
ASIC Power Supplies In:  
- Desktops, Notebooks and Graphic Cards  
- Set Top Boxes, Printers and Copiers  
DSP and FPGA Power Supplies  
SMPS Post-Regulator  
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.
