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.
