LP3878-ADJ  
SNVS311D MAY 2005REVISED FEBRUARY 2015  
LP3878-ADJ Micropower 800-mA Low-Noise "Ceramic Stable" Adjustable Voltage  
Regulator for 1-V to 5-V Applications  
1 Features  
3 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 V.  
1
Input Supply Voltage: 2.5 V to 16V  
Output Voltage Range: 1 V to 5.5 V  
Designed for Use With Low-ESR Ceramic  
Capacitors  
Using an optimized VIP (Vertically Integrated PNP)  
Very Low Output Noise  
process,  
the  
LP3878-ADJ  
delivers  
superior  
8-Lead SO PowerPAD™ and WSON Surface-  
Mount Packages  
performance:  
Ground Pin Current: Typically 5.5 mA at 800-mA  
load, and 180 µA at 100-µA load.  
Low Power Shutdown: The LP3878-ADJ draws  
less than 10-μA quiescent current when the  
SHUTDOWN pin is pulled low.  
< 10-μA Quiescent Current in Shutdown  
Low Ground Pin Current at all Loads  
Overtemperature and Overcurrent Protection  
–40°C to 125°C Operating Junction Temperature  
Range  
Precision Output: Ensured output voltage  
accuracy is 1% at room temperature.  
Low Noise: Broadband output noise is only 18 μV
