LP2985 Micropower 150 mA Low-Noise Ultra Low-Dropout Regulator in SOT-23 and micro SMD

Packages

July 1, 2007

LP2985

Micropower 150 mA Low-Noise Ultra Low-Dropout

Regulator in SOT-23 and micro SMD Packages

Designed for Use with Very Low ESR Output Capacitors

General Description

The LP2985 is a 150 mA, fixed-output voltage regulator de-

signed to provide ultra low-dropout and low noise in battery

powered applications.

Using an optimized VIP

(Vertically Integrated PNP) process,

the LP2985 delivers unequalled performance in all specifica-

tions critical to battery-powered designs:

Dropout Voltage:

Typically 300 mV @ 150 mA load, and

7 mV @ 1 mA load.

Ground Pin Current:

Typically 850 µA @ 150 mA load, and

75 µA @ 1 mA load.

Enhanced Stability:

The LP2985 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 micro SMD 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 2.5V to 5.0V, are available as

standard products. Consult factory for custom voltages.
