DESCRIPTION
The LP2980-N is a 50 mA, fixed-output voltage
regulator designed specifically to meet the
requirements of battery-powered applications.
Using an optimized VIP (Vertically Integrated PNP)
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.
Minimum Part Count. Requires only 1 μF of external
capacitance on the regulator output.
Precision Output. 0.5% tolerance output voltages
available (A grade).
5.0V, 4.7V, 3.3V, 3.0V and 2.5V versions available as
standard products.
