LP2966
Dual 150mA Ultra Low-Dropout Regulator
General Description
The LP2966 dual ultra low-dropout (LDO) regulator operates
from a +2.70V to +7.0V input supply. Each output delivers
150mAover full temperature range. The IC operates with ex-
tremely low drop-out voltage and quiescent current, which
makes it very suitable for battery powered and portable ap-
plications. Each LDO in the LP2966 has independent shut-
down capability. The LP2966 provides low noise perfor-
mance with low ground pin current in an extremely small
MSOP-8 package (refer to package dimensions and connec-
tion diagram for more information on MSOP-8 package). 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 re-
quest with minimum orders. In all, 256 voltage combinations
are possible.
Key Specifications
Dropout Voltage:
Varies linearly with load current. Typically
0.9 mV at 1mA load current and 135mV at 150mA load cur-
rent.
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.

Typical Application Circuit
DS100850-30
*SD1 and SD2 must be actively terminated through a pull up resistor. Tie to V
IN
if not used.
**ERROR1 and ERROR2 are open drain outputs. These pins must be connected to ground if not used.
# Minimum output capacitance is 1μF to insure stability over full load current range. More capacitance improves superior dynamic performance and provides
additional stability margin.
