LP2966EP
Enhanced Plastic Dual 150mA Ultra Low-Dropout
Regulator
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.

Key Specifications
Dropout Voltage: Varies linearly with load current. Typically
0.9 mV at 1mA load current and 135mV at 150mA load
current.
Ground Pin Current: Typically 300µA at 1mA load current
and 340µA at 100mA load current (with one shutdown pin
pulled low).
Shutdown Mode: Less than 1µA quiescent current when
both shutdown pins are pulled low.
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.
