LP2982 Micropower 50 mA Ultra Low-Dropout Regulator

March 2000

LP2982

Micropower 50 mA Ultra Low-Dropout Regulator

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

鈩?/div>

(Vertically Integrated PNP) pro-

cess, the LP2982 delivers unequaled performance in all

specifications critical to battery-powered designs:

Dropout Voltage:

Typically 120 mV

50 mA load, and 7 mV

1 mA load.

Ground Pin Current:

Typically 375 碌A

50 mA load, and

80 碌A

1 mA load.

Sleep Mode:

Less than 1 碌A 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 碌V (typical).

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

as standard products.

Features
