LP3963/LP3966

3A Fast Ultra Low Dropout Linear Regulators

General Description

Features

n Ultra low dropout voltage

The LP3963/LP3966 series of fast ultra low-dropout linear

regulators operate from a +2.5V to +7.0V input supply. Wide

range of preset output voltage options are available. These

ultra low dropout linear regulators respond very fast to step

changes in load which makes them suitable for low voltage

microprocessor applications. The LP3963/LP3966 are de-

veloped on a CMOS process which allows low quiescent

current operation independent of output load current.This

CMOS process also allows the LP3963/LP3966 to operate

under extremely low dropout conditions.

n Low ground pin current

n Load regulation of 0.06%

n 15µA quiescent current in shutdown mode

n Guaranteed output current of 3A DC

n Available in TO-263 and TO-220 packages

n Output voltage accuracy 1.5%

n Error flag indicates output status (LP3963)

n Sense option improves better load regulation (LP3966)

n Extremely low output capacitor requirements

n Overtemperature/overcurrent protection

Dropout Voltage: Ultra low dropout voltage; typically 80mV

at 300mA load current and 800mV at 3A load current.

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

Ground Pin Current: Typically 6mA at 3A load current.

Shutdown Mode: Typically 15µA quiescent current when

the shutdown pin is pulled low.

Applications

n Microprocessor power supplies

n GTL, GTL+, BTL, and SSTL bus terminators

n Power supplies for DSPs

n SCSI terminator

Error Flag: Error flag goes low when the output voltage

drops 10% below nominal value (for LP3963).

SENSE: Sense pin improves regulation at remote loads.

(For LP3966)

n Post regulators

Precision Output Voltage: Multiple output voltage options

n High efficiency linear regulators

n Battery chargers

are available ranging from 1.2V to 5.0V and adjustable, with

a guaranteed accuracy of 1.5% at room temperature, and

3.0% over all conditions ( varying line, load, and tempera-

n Other battery powered applications

ture).

Typical Application Circuits

DS101267-1

# Minimum output capacitance is 10 µF to ensure stability over full load current range. More capacitance provides superior dynamic performance and additional

stability margin.

*SD and ERROR pins must be pulled high through a 10kΩ pull-up resistor. Connect the ERROR pin to ground if this function is not used. See applications sec-

tion for more information.
