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.
