SLVS522O –JULY 2004–REVISED JANUARY 2015

LP2985 150-mA Low-noise Low-dropout Regulator With Shutdown

1 Features

3 Description

The LP2985 family of fixed-output, low-dropout

regulators offers exceptional, cost-effective

performance for both portable and nonportable

applications. Available in voltages of 1.8 V, 2.5 V, 2.8

V, 2.9 V, 3 V, 3.1 V, 3.3 V, 5 V, and 10 V, the family

has an output tolerance of 1% for the A version (1.5%

for the non-A version) and is capable of delivering

150-mA continuous load current. Standard regulator

features, such as overcurrent and overtemperature

protection, are included.
