3 Description
The LP2983 is a 150-mA, fixed-output voltage
regulator designed to provide tight voltage regulation
in applications with output voltages ≤ 1.2 V.
Using an optimized vertically integrated PNP (VIP)
process, the LP2983 delivers unequaled performance
in all critical specifications:
• Ground pin current: Typically 825 μA at a 150-mA
load, and 75 μA at a 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.
• Precision output: 1% tolerance output voltages
available (A grade).
• Smallest possible size: SOT-23 package uses
absolute minimum board space.
