It delivers a regulated 1.5V rail from an input up to 13V, with a maximum dropout voltage of 1.4V at full load. ## Thermal and protection features for industrial duty Operating from -40°C to 125°C, this LDO suits industrial control, telecom, and automotive environments where ambient temperatures push beyond commercial range. Built-in over-current and over-temperature protection let the regulator survive output shorts and sustained overloads without external crowbar circuitry. The 7 mA quiescent current is typical for a 5A LDO — not a micropower part, but acceptable for always-on rails in equipment with a modest standby budget. ## PSRR and ripple rejection at line frequency PSRR is specified at 60 to 72 dB at 120 Hz — the fundamental ripple frequency from a full-wave rectified 60 Hz mains input. 60 dB rejection means the output ripple is 1/1000th of the input ripple; a 100 mVpp input hum drops to 100 µVpp at the output, which is clean enough for most analog and digital loads. ## Active lifecycle and compliance status Because it is an active TI catalog item, the LMS1585AIS-1.5/NOPB is sourced through authorized distribution channels with full factory traceability and warranty.","metaTitle":"LMS1585AIS-1.5/NOPB TI LDO, 5A Fixed 1.5V, DDPAK","metaDescription":"Texas Instruments LMS1585AIS-1.5/NOPB 5A LDO, fixed 1.5V output, 1.4V dropout, -40 to 125°C, DDPAK/TO-263-3.
