LP2992

Micropower 250 mA Low-Noise Ultra Low-Dropout

Regulator in SOT-23 and LLP Packages

Designed for Use with Very Low ESR Output Capacitors

General Description

The LP2992 is a 250 mA, fixed-output voltage regulator

designed to provide ultra low-dropout and low noise in bat-

tery powered applications.

Using an optimized VIP

cess, the LP2992 delivers unequalled performance in all

specifications critical to battery-powered designs:

Dropout Voltage: Typically 450 mV

5 mV

Ground Pin Current: Typically 1500 µA

75 µA

Enhanced Stability: The LP2992 is stable with output ca-

pacitor 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.
