LP2982

Micropower 50 mA Ultra Low-Dropout Regulator in

SOT-23 and micro SMD Packages

General Description

The LP2982 is a 50 mA, fixed-output voltage regulator de-

signed to provide ultra low dropout and lower noise in battery

powered applications.

Using an optimized VIP

cess, the LP2982 delivers unequaled performance in all

specifications critical to battery-powered designs:

Dropout Voltage: Typically 120 mV

Ground Pin Current: Typically 375 µA

80 µA

Sleep Mode: Less than 1 µA quiescent current when on/off

pin is pulled low.

Smallest Possible Size: SOT-23 and micro SMD packages

use absolute minimum board space.

Precision Output: 1.0% tolerance output voltages available

(A grade).

Low Noise: By adding an external bypass capacitor, output

noise can be reduced to 30 µV (typical).

Ten output voltage versions, from 2.5V to 5.0V, are available

as standard products.
