process,  
the  
LP2980-N  
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.  
Over-Temperature and Over-Current  
Protection  
Minimum Part Count. Requires only 1 μF of external  
40°C to +125°C Junction Temperature Range  
capacitance on the regulator output.
