The quiescent current of 225 µA and max supply current of 325 µA keep the part efficient for always-on or battery-backed rails. Protection covers over-current, over-temperature, reverse polarity, and UVLO, so it survives a miswired bench or a hot reflow cycle. ## Package and mounting The SOT-223-6 package is a tabbed surface-mount part with moderate thermal mass. The exposed pad on the bottom side needs a good solder joint to the board's copper pour for heat sinking — check your pad layout for a thermal via cluster under the tab. Rework with hot air is doable if the board has enough preheat; the tab can act as a heat sink that makes the part stubborn to lift. ## Where it fits and the temperature range Rated for -40°C to 125°C, this LDO suits industrial control cabinets, outdoor telecom gear, automotive body electronics, and engine-bay-adjacent modules that see under-hood heat. ## Sourcing and lifecycle TI lists the TPS72501DCQ as Active and ROHS3 compliant. No end-of-life notice or last-time-buy window is in the record, so this part is safe to qualify into a new BOM or maintain as a production line item.","metaTitle":"TI TPS72501DCQ LDO Regulator, Adjustable 1A, SOT-223-6","metaDescription":"Texas Instruments TPS72501DCQ adjustable LDO regulator, 1A output, 0.28V dropout at 1A, PSRR 60dB at 1kHz, -40°C to 125°C, SOT-223-6.
