General Description

The LP2992 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 LP2992 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.
