LP2982  
SNVS128K –MARCH 2000–REVISED JUNE 2016  
LP2982 50-mA Micropower Ultra-Low-Dropout LDO in SOT-23 Package  
1 Features  
3 Description  
The LP2982 is a 50-mA, fixed-output voltage LDO  
designed to provide ultra-low dropout and lower noise  
in battery-powered applications.

Ultra-Low-Dropout Voltage  
Ensured 50-mA Output Current  
Using an optimized vertically integrated PNP (VIP)  
process, the LP2982 delivers unequaled performance  
in all specifications critical to battery-powered  
designs:  
Typical Dropout Voltage 180 mV at 80 mA  
Requires Minimum External Components  
< 1 μA Quiescent Current When Shut Down  
Low Ground Pin Current at All Loads  
Output Voltage Accuracy 1% (A Grade)  
High Peak Current Capability (150 mA Typical)  
Wide Supply Voltage Range (16 V Maximum)  
Low ZOUT 0.3 Ω Typical (10 Hz to 1 MHz)  
Overtemperature and Overcurrent Protection  
−40°C to +125°C Junction Temperature Range  
Dropout Voltage: Typically 120 mV at 50 mA load,  
and 7 mV at 1 mA load.  
Ground Pin Current: Typically 375 μA at 50 mA load,  
and 80 μA at 1 mA load.  
Sleep Mode: Less than 1-μA quiescent current when  
ON/OFF pin is pulled low.  
Precision Output: 1% tolerance output voltages  
available (A grade).  
2 Applications  
Low Noise: By adding an external bypass capacitor,  
output noise can be reduced to 30 μV (typical).
