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.
