LP2966

Dual 150mA Ultra Low-Dropout Regulator

General Description

Features

n Ultra low drop-out voltage

n Low ground pin current

The LP2966 dual ultra low-dropout (LDO) regulator operates

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

150mA over 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.

1µA quiescent current in shutdown mode

n Independent shutdown of each LDO regulator

n Output voltage accuracy 1%

n Guaranteed 150mA output current at each output

n Low output noise

n Error Flags indicate status of each output

n Available in MSOP-8 surface mount packages

n Low output capacitor requirements (1µF)

n Operates with Low ESR ceramic capacitors in most

applications

n Over temperature/over current protection

n -40˚C to +125˚C junction temperature range

Key Specifications

Dropout Voltage: Varies linearly with load current. Typically

0.9 mV at 1mA load current and 135mV at 150mA load cur-

rent.

Applications

n Cellular and Wireless Applications

n Palmtop/Laptop Computer

n GPS systems

Ground Pin Current: Typically 300µA at 1mA load current

and 340µA at 100mA load current (with one shutdown pin

pulled low).

n Flat panel displays

n Post regulators

n USB applications

n Hand held equipment and multimeters

n Wireless data terminals

n Other battery powered applications

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 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.
