LP3872/LP3875 1.5A Fast Ultra Low Dropout Linear Regulators

Check for Samples: LP3872, LP3875

FEATURES

DESCRIPTION

The LP3872/LP3875 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 quickly to step changes in

load, which makes them suitable for low voltage

microprocessor applications. The LP3872/LP3875 are

developed on a CMOS process which allows low

quiescent current operation independent of output

load current. This CMOS process also allows the

LP3872/LP3875 to operate under extremely low

dropout conditions.

•

Ultra Low Dropout Voltage

Low Ground Pin Current

Load Regulation of 0.06%

10nA Quiescent Current in Shutdown Mode

Ensured Output Current of 1.5A DC

Available in DDPAK/TO-263, TO-220 and

SOT-223 Packages

•

Output Voltage Accuracy ± 1.5%

Error Flag Indicates Output Status

Sense Option Improves Load Regulation

Minimum Output Capacitor Requirements

Overtemperature/Overcurrent Protection

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

Dropout Voltage: Ultra low dropout voltage; typically

38mV at 150mA load current and 380mV at 1.5A load

current.

Ground Pin Current: Typically 6mA at 1.5A load

current.

APPLICATIONS

Shutdown Mode: Typically 10nA quiescent current

when the shutdown pin is pulled low.

•

Microprocessor Power Supplies

GTL, GTL+, BTL, and SSTL Bus Terminators

Power Supplies for DSPs

SCSI Terminator

Error Flag: Error flag goes low when the output

voltage drops 10% below nominal value.

SENSE: Sense pin improves regulation at remote

loads.

Post Regulators

High Efficiency Linear Regulators

Battery Chargers

Precision Output Voltage: Multiple output voltage

options are available ranging from 1.8V to 5.0V with a

specified accuracy of ±1.5% at room temperature,

and ±3.0% over all conditions (varying line, load, and

temperature).

Other Battery Powered Applications

TYPICAL APPLICATION CIRCUITS

*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.
