LP2982  
Micropower 50 mA Ultra Low-Dropout Regulator  
General Description  
The LP2982 is a 50 mA, fixed-output voltage regulator de-  
signed to provide ultra low dropout and lower noise in battery  
powered applications.  
Features  
n Ultra low dropout voltage  
n Guaranteed 50 mA output current  
@
n Typical dropout voltage 180 mV 80 mA  
Using an optimized VIP (Vertically Integrated PNP) pro-  
n Smallest possible size (SOT-23, micro SMD package)  
n Requires minimum external components  
cess, the LP2982 delivers unequaled performance in all  
specifications critical to battery-powered designs:  
<
n
1 µA quiescent current when shutdown  
@
Dropout Voltage: Typically 120 mV 50 mA load, and 7 mV  
n Low ground pin current at all loads  
@
1 mA load.  
n Output voltage accuracy 1.0% (A Grade)  
n High peak current capability (150 mA typical)  
n Wide supply voltage range (16V max)  
n Low ZOUT 0.3typical (10 Hz to 1 MHz)  
n Overtemperature/overcurrent protection  
n −40˚C to +125˚C junction temperature range  
n Custom voltages available  
@
Ground Pin Current: Typically 375 µA 50 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-23 and micro SMD packages  
use absolute minimum board space.  
Precision Output: 1.0% tolerance output voltages available  
(A grade).  
Applications  
Low Noise: By adding an external bypass capacitor, output  
noise can be reduced to 30 µV (typical).  
n Cellular Phone  
n Palmtop/Laptop Computer  
n Personal Digital Assistant (PDA)  
n Camcorder, Personal Stereo, Camera  
Ten output voltage versions, from 2.5V to 5.0V, are available  
as standard products.
