3 Description

The TLV751 is a dual, adjustable, 500-mA lowdropout

(LDO) regulator. This device is available in a

small, 10-pin, 2-mm × 2-mm WSON package and

consumes 25-μA quiescent current while providing

fast line and load transient response. The TLV751

features an low dropout of 130 mV that can help

improve the overall power efficiency.

The TLV751 wide input-and-output voltage ranges,

when combined with its output current capability in a

small printed circuit board (PCB) footprint help

support a wide variety of applications from sensor

supplies, to auxiliary rails, and modern

microcontrollers with lower core voltages.

The TLV751 is stable with small ceramic output

capacitors, allowing for a small overall solution size.

A precision band-gap and error amplifier provides

high accuracy of 1.5% (max) over temperature. This

device includes integrated thermal shutdown, current

limit, active output-discharge, and undervoltage

lockout (UVLO) features. The TLV751 has an internal

fold-back current-limit to reduce thermal dissipation

during short-circuit events.
