LP3876-ADJ 3A Fast Ultra Low Dropout Linear Regulator

Check for Samples: LP3876-ADJ

FEATURES

DESCRIPTION

The LP3876-ADJ fast ultra low-dropout linear

regulators operate from a +2.5V to +7.0V input

supply. These ultra low dropout linear regulators

respond very quickly to step changes in load, which

makes them suitable for low voltage microprocessor

applications. The LP3876-ADJ is developed on a

CMOS process which allows low quiescent current

operation independent of output load current. This

CMOS process also allows the LP3876-ADJ to

operate under extremely low dropout conditions.

•

Ultra Low Dropout Voltage

Low Ground Pin Current

Load Regulation of 0.08%

1µA Quiescent Current in Shutdown Mode

Specified Output Current of 3A DC

Available in DDPAK/TO-263 and TO-220

Packages

•

Minimum output Capacitor Requirements

Overtemperature/Overcurrent Protection

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

Dropout Voltage: Ultra low dropout voltage; typically

80mV at 300mA load current and 800mV at 3A load

current.

APPLICATIONS

Ground Pin Current: Typically 6mA at 3A load

current.

•

Microprocessor Power Supplies

GTL, GTL+, BTL, and SSTL bus terminators

Power Supplies for DSPs

SCSI Terminator

Shutdown Mode: Typically 1µA quiescent current

when the shutdown pin is pulled low.

Adjustable Output Voltage: The output voltage may

be programmed via two external resistors.
