LP2966EP

Enhanced Plastic Dual 150mA Ultra Low-Dropout

Regulator

Shutdown Mode: Less than 1µA quiescent current when

both shutdown pins are pulled low.

General Description

The LP2966EP dual ultra low-dropout (LDO) regulator oper-

ates from a +2.70V to +7.0V input supply. Each output

delivers 150mA over full temperature range. The IC operates

with extremely low drop-out voltage and quiescent current,

which makes it very suitable for battery powered and por-

table applications. Each LDO in the LP2966EP has indepen-

dent shutdown capability. The LP2966EP provides low noise

performance with low ground pin current in an extremely

small MSOP-8 package (refer to package dimensions and

connection diagram for more information on MSOP-8 pack-

age). A wide range of preset voltage options are available for

each output. In addition to the voltage combinations listed in

the ordering information table, many more are available

upon request with minimum orders. In all, 256 voltage com-

binations are possible.

Error Flag: Open drain output, goes low when the corre-

sponding output drops 10% below nominal.

Precision Output Voltage: Multiple output voltage options

available ranging from 1.8V to 5.0V with a guaranteed accu-

racy of 1% at room temperature.
