LP2981  
Micropower 100 mA Ultra Low-Dropout Regulator  
General Description  
The LP2981 is a 100 mA, fixed-output voltage regulator de-  
signed specifically to meet the requirements of  
battery-powered applications.  
Features  
n Ultra low dropout voltage  
n Output voltage accuracy 0.75% (A Grade)  
n Guaranteed 100 mA output current  
Using an optimized VIP (Vertically Integrated PNP) pro-  
n Smallest possible size (SOT-23, micro SMD package)  
cess, the LP2981 delivers unequaled performance in all  
specifications critical to battery-powered designs:  
<
n
1 µA quiescent current when shutdown  
n Low ground pin current at all load currents  
n High peak current capability (300 mA typical)  
n Wide supply voltage range (16V max)  
n Fast dynamic response to line and load  
n Low ZOUT over wide frequency range  
n Overtemperature/overcurrent protection  
n −40˚C to +125˚C junction temperature range  
@
Dropout Voltage. Typically 200 mV  
100 mA load, and  
@
7 mV 1 mA load.  
@
Ground Pin Current. Typically 600 µA 100 mA load, and  
@
80 µA 1 mA load.  
Sleep Mode. Less than 1 µA quiescent current when ON/  
OFF pin is pulled low.  
Smallest Possible Size. SOT-23and micro SMD packages  
use an absolute minimum board space.  
Applications  
Precision Output. 0.75% tolerance output voltages avail-  
able (A grade).  
n Cellular Phone  
n Palmtop/Laptop Computer  
n Personal Digital Assistant (PDA)  
n Camcorder, Personal Stereo, Camera  
Eleven voltage options, from 2.5V to 5.0V, are available as  
standard products.
