illustrate

The LP2992 is a 250 mA, fixed output voltage regulator that provides a low noise design for ultra-low dropout and battery-powered applications.

Using an optimized VIP (vertically integrated PNP) process, the LP2992 delivers unmatched performance in a variety of specifications critical to battery-powered designs:

Dropout voltage: typically 450 mV @ 250 mA load and 5 mV @ 1 mA load.

Ground pin current: typically 1500μ A@ 250 mA load, and 75μ A@ 1 mA load.

Enhanced Stability: The LP2992 is stable, with an ESR of 5 low mΩ for output capacitors, allowing the use of ceramic capacitors on the output.

Sleep Mode: The ON/OFF pins with quiescent current below 1μA are pulled low.

Smallest possible size: The SOT-23 and LLP packages use the absolute minimum board space.

Precision output: 1% accurate output voltage (Class A).

Low noise: Output noise can be reduced by 30 μV (typical) by adding a 10 nF bypass capacitor.

Multiple voltage options, from 1.5V to 5.0V, are available as standard. Custom voltage consulting plant.
