Texas Instruments TLV751 Dual Adjustable 500mA LDO Regulator
Texas Instruments TLV751 Dual Adjustable 500mA LDO Regulator is available in a small, 10-pin, 2mm×2mm WSON package and consumes 25µA quiescent current while providing fast line and load transient response. The TLV751 features a low dropout of 130mV that can help improve overall power efficiency. It offers wide input-and-output voltage ranges and 500mA output current capability in a small printed circuit board (PCB) footprint. This feature helps support various applications, from sensor supplies to auxiliary rails and modern microcontrollers with lower core voltages.
The Texas Instruments TLV751 is stable with small ceramic output capacitors, allowing for a small overall solution size. A precision band-gap and error amplifier provides a 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.
