General 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 unequalled 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).
