Its PSRR of 57 dB at 1 kHz dropping to 35 dB at 1 MHz means it filters switching-noise ripple from a buck converter feeding a sensor or MCU rail — the roll-off above 1 MHz is where the regulator loses rejection, so keep the upstream switcher's fundamental below that. Quiescent current is 36 µA, low enough for always-on automotive modules that stay powered during key-off. The Enable and Power Good control features let the system sequence the rail and monitor its state without an external supervisor. ## AEC-Q100 qualification and 125 °C junction The 8-SON package with wettable flank enables automatic optical inspection of the solder joints — a requirement for automotive assembly lines. Product status is Active, meaning Texas Instruments is still manufacturing it. No last-time-buy window has been announced. ## Dropout headroom and protection set Maximum dropout voltage is 0.6 V at 500 mA. For a 1.15 V output, the input must stay above 1.75 V worst-case to maintain regulation — a 3.3 V or 5 V rail provides enough margin. The part includes Over Current, Over Temperature, and Under Voltage Lockout (UVLO) protection, so a shorted load or thermal runaway shuts down the regulator before the downstream circuit sees an overvoltage. Compared to the TPS70612DBVT (150 mA, 80 dB PSRR at 10 Hz) or the TPS7A0313PDBVR (200 mA, 55 dB at 1 kHz), the TPS745115PQWDRBRQ1 offers higher output current and a wider PSRR bandwidth — the 57 dB at 1 kHz extends to 35 dB at 1 MHz, whereas the TPS70612DBVT's PSRR is specified only below 1 kHz. If your rail needs >200 mA and rejection at switching frequencies, this part fills that gap.","metaTitle":"TPS745115PQWDRBRQ1 LDO Regulator – 500 mA, AEC-Q100","metaDescription":"Texas Instruments TPS745115PQWDRBRQ1 – automotive LDO, 500 mA output, 1.15 V fixed, PSRR 57 dB at 1 kHz, 36 µA Iq, active production.
