FEATURES  
DESCRIPTION  
The LP3871/LP3874 series of fast ultra low-dropout  
linear regulators operate from a +2.5V to +7.0V input  
supply. Wide range of preset output voltage options  
are available. These ultra low dropout linear  
regulators respond very quickly to step changes in  
load, which makes them suitable for low voltage  
microprocessor applications. The LP3871/LP3874 are  
developed on a CMOS process which allows low  
quiescent current operation independent of output  
load current. This CMOS process also allows the  
LP3871/LP3874 to operate under extremely low  
dropout conditions.

High Efficiency Linear Regulators  
Battery chargers  
Precision Output Voltage: Multiple output voltage  
options are available ranging from 1.8V to 5.0V with a  
ensured accuracy of ±1.5% at room temperature, and  
±3.0% over all conditions (varying line, load, and  
temperature).
