The 100 µA quiescent current (350 µA max supply) keeps the overhead low for always-on rails in battery-backed or standby domains. Operating junction temperature spans -40°C to 125°C, so it fits industrial enclosures, outdoor telecom cabinets, and under-hood automotive modules that see underhood ambient heat. The protection set — over-current, over-temperature, reverse polarity, and under-voltage lockout — means it can sit on a field-wired board without dying on the first misconnection. ## Protection features for field-deployed rails Reverse polarity protection is uncommon on LDOs at this current level — it clamps the pass element so a reversed battery connection doesn't dump current through the substrate. The UVLO holds the output off until the input rises above the internal threshold, preventing the load from seeing a brown-out voltage during startup or sag. Over-current and thermal shutdown handle the rest: foldback limits the current, and the die shuts down if the junction hits the thermal limit. ## Sourcing and lifecycle The TPS7A8001DRBR carries an active lifecycle status from Texas Instruments. The part is ROHS3 compliant, which covers EU and most global markets without exemption paperwork.","metaTitle":"TI TPS7A8001DRBR LDO Regulator, 1A Adjustable, 8-SON","metaDescription":"TPS7A8001DRBR from TI: 1A adjustable LDO, 0.8V-6V output, PSRR 48dB~38dB (100Hz-1MHz), -40°C~125°C, 8-SON.
