Description
The TLV751 is a dual, adjustable, 500-mA low-dropout (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.
