LP3961/LP3964 800mA Fast Ultra Low Dropout Linear Regulators

Check for Samples: LP3961, LP3964

FEATURES

DESCRIPTION

The LP3961/LP3964 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 LP3961/LP3964 are

developed on a CMOS process which allows low

quiescent current operation independent of output

load current. This CMOS process also allows the

LP3961/LP3964 to operate under extremely low

dropout conditions.

•

Ultra Low Dropout Voltage

Low Ground Pin Current

Load Regulation of 0.02%

15µA Quiescent Current in Shutdown Mode

Specified Output Current of 0.8A DC

Available in SOT-223, SFM/TO-263 and TO-220

Packages

•

Output Voltage Accuracy ± 1.5%

Error Flag Indicates Output Status (LP3961)

Sense Option Improves Better Load

Regulation (LP3964)

Dropout Voltage: Ultra low dropout voltage; typically

24mV at 80mA load current and 240mV at 800mA

load current.

•

Extremely Low Output Capacitor

Requirements

Ground Pin Current: Typically 4mA at 800mA load

current.

•

Overtemperature/Overcurrent Protection

−40°C to +125°C Junction Temperature Range

Shutdown Mode: Typically 15µA quiescent current

when the shutdown pin is pulled low.

APPLICATIONS

Error Flag:Error flag goes low when the output

voltage drops 10% below nominal value (for LP3961).

•

Microprocessor Power Supplies

GTL, GTL+, BTL, and SSTL Bus Terminators

Power Supplies for DSPs

SCSI Terminator

SENSE: Sense pin improves regulation at remote

loads. (For LP3964)

Precision Output Voltage: Multiple output voltage

options are available ranging from 1.2V to 5.0V and

adjustable (LP3964), with a specified accuracy of

±1.5% at room temperature, and ±3.0% over all

conditions (varying line, load, and temperature).

Post Regulators

High Efficiency Linear Regulators

Battery Chargers

Other Battery Powered Applications

Typical Application Circuits

A. 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 Application Hints for more information.
