DESCRIPTION
The LP2983 is a 150 mA, fixed-output voltage
regulator designed to provide tight voltage regulation
in applications with output voltages ≤ 1.2V.
Using an optimized VIP™ (Vertically Integrated PNP)
process, the LP2983 delivers unequaled performance
in all critical specifications:
Ground Pin Current: Typically 825 µA @ 150 mA
load, and 75 µA @ 1 mA load.
Enhanced Stability: The LP2983 is stable with
output capacitor ESR down to zero, which allows the
use of ceramic capacitors on the output.
Smallest Possible Size: SOT-23 package uses
absolute minimum board space.
Precision Output: 1% tolerance output voltages
available (A grade).
