The exposed pad is the primary thermal path — the PCB land pattern must include a thermal via array under the pad to pull heat into the inner ground plane. The wettable-flank termination lets the AOI system verify the solder fillet on the package side, which is a requirement for many automotive assembly lines. Mounting is surface-mount with wettable flank — no through-hole option. The package accepts Tape & Reel or Cut Tape delivery, so the reel quantity and feeder setup need to match the pick-and-place bill. ## Dropout and quiescent: what the numbers mean for the rail The 265 mV maximum dropout at 1 A output tells you the headroom needed between the input rail and the 5 V output. With a 5 V fixed output, the input must stay above 5.265 V worst-case to keep the output in regulation — a 5.5 V rail gives 235 mV margin, but a 5.0 V rail will not hold regulation. The 36 µA typical quiescent current is the LDO's own draw; in an always-on ECU module that sees ignition-off standby, that Iq sits below the module's sleep budget. The 1 A continuous output rating is enough to power a sensor cluster, a CAN transceiver plus an MCU, or a small solenoid driver. The protection features — over-current, over-temperature, and under-voltage lockout — cover the common fault cases on an automotive power rail without requiring an external supervisor. ## Automotive temperature grade and qualification Rated for -40°C to +125°C ambient, the TPS74650PQWDRBRQ1 is qualified to AEC-Q100. That means it passed the full suite of automotive stress tests: temperature cycling, high-temperature operating life, ESD, and latch-up. The 125°C upper limit covers under-hood and cabin-mounted ECUs that see under-hood soak temperatures on a hot day. The series is listed as Automotive, AEC-Q100 — this is the standard automotive IC qualification, not a custom screening. The part carries the full production PPAP documentation from Texas Instruments.","metaTitle":"TPS74650PQWDRBRQ1 1A LDO, 5V Fixed, AEC-Q100, 8-SON","metaDescription":"Texas Instruments TPS74650PQWDRBRQ1 automotive LDO, 1A output, 5V fixed, 265mV dropout at 1A, 36µA Iq, AEC-Q100, 8-SON wettable flank.
