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

extremely low drop-out voltage and quiescent current, which

makes it very suitable for battery powered and portable

applications. Each LDO in the LP2966 has independent

shutdown 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

request with minimum orders. In all, 256 voltage combina-

tions 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

current.

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

10085030

*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.
