Listed as active in production, this part is suitable for current-design procurement and new builds requiring a 5 A linear rail. ## Dropout and PSRR at 5 A Maximum dropout voltage is 1.4 V at the full 5 A load — the input must stay above 2.9 V to maintain regulation at 1.5 V out. PSRR measures 60 to 72 dB at 120 Hz, typical for a 5 A LDO; the lower end of the band applies at full output current where the pass transistor gain drops. ## TO-220-3 through-hole, 0 to 125°C Housed in a TO-220-3 through-hole package, the tab is the output (Vout) — the copper pad area on the PCB or a heatsink sets the thermal impedance for 5 A dissipation. Rated for 0°C to 125°C operating junction temperature, which covers commercial and most industrial ambient ranges when properly heatsunk. ## Protection and quiescent draw Built-in over-current and over-temperature protection latch the part off during fault conditions — recovery requires cycling the input or load. Quiescent current is 7 mA typical, with a maximum supply current of 13 mA, both steady regardless of load — the dropout FET's gate drive dominates the overhead. ## Sourcing and compliance ROHS3 compliant per the NOPB suffix; no other regulatory certifications (UL, IEC) are listed in the record for this order code.","metaTitle":"Texas Instruments LMS1585ACT-1.5/NOPB LDO, 1.5V Fixed, 5A","metaDescription":"Texas Instruments LMS1585ACT-1.5/NOPB 5A LDO regulator, fixed 1.5V output, TO-220-3, active production.
