DESCRIPTION
The LP2981-N is a 100 mA, fixed-output voltage
regulator designed specifically to meet the
requirements of battery-powered applications.
Using an optimized VIP (Vertically Integrated PNP)
process,
the
LP2981-N
delivers
unequaled
performance in all specifications critical to battery-
powered designs:
Dropout Voltage.
Typically 200 mV @ 100 mA load,
and 7 mV @ 1 mA load.
Ground Pin Current.
Typically 600
μA
@ 100 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.
0.75% tolerance output voltages
available (A grade).
Nine voltage options, from 2.5V to 5.0V, are available
as standard products.
