FEATURES  
DESCRIPTION  
The LP2982 is  
regulator designed to provide ultra low dropout and  
lower noise in battery powered applications.  
a 50 mA, fixed-output voltage

Ensured 50 mA Output Current  
Typical Dropout Voltage 180 mV @ 80 mA  
Requires Minimum External Components  
< 1 μA Quiescent Current when Shutdown  
Low Ground Pin Current at All Loads  
Output Voltage Accuracy 1.0% (A Grade)  
High Peak Current Capability (150 mA Typical)  
Wide Supply Voltage Range (16V Max)  
Low ZOUT 0.3Ω Typical (10 Hz to 1 MHz)  
Over-Temperature/Over-Current Protection  
−40°C to +125°C Junction Temperature Range  
Using an optimized VIP™ (Vertically Integrated PNP)  
process, the LP2982 delivers unequaled performance  
in all specifications critical to battery-powered  
designs:  
Dropout Voltage: Typically 120 mV @ 50 mA load,  
and 7 mV @ 1 mA load.  
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.  
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).
