LP2983 General Description


The LP2983 is a 150 mA, fixed-output voltage regulator designed to provide tight voltage regulation in applications with output voltages1.2V.

Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2983 delivers unequalled performance in all critical specifications:

Ground Pin Current: Typically 825 A @ 150 mA load, and 75 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.

Smallest Possible Size: SOT-23 package uses absolute minimum board space.

Precision Output: 1% tolerance output voltages available (A grade).
