Description

The LP2992AIM5-1.5 is a 250 mA, fixed-output voltage regulator designed to provide ultra low-dropout and low noise in battery powered applications. Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2992 delivers unequalled performance in all specifications critical to battery-powered designs: Dropout Voltage: Typically 450 mV @ 250 mA load, and 5 mV @ 1 mA load. Ground Pin Current: Typically 1500 µA @ 250 mA load, and 75 µA @ 1 mA load. Enhanced Stability: 

 The LP2992AIM5-1.5 is stable with output capacitor ESR as low as 5 mΩ, which allows the use of ceramic capacitors on the output. Sleep Mode: Less than 1 µA quiescent current when ON/OFF pin is pulled low. Smallest Possible Size: SOT-23 and LLP packages use absolute minimum board space. Precision Output: 1% tolerance output voltages available (A grade). Low Noise: By adding a 10 nF bypass capacitor, output noise can be reduced to 30 µV (typical). Multiple voltage options, from 1.5V to 5.0V, are available as standard products. Consult factory for custom voltages.
