The maximum dropout voltage of 0.465V at full load means the input rail must stay above 1.665V across the operating range to maintain regulation — a 5V or 3.3V supply provides comfortable headroom, but a 1.8V rail at its low tolerance edge may push the dropout margin tight. Quiescent current is 36 µA typical, making this LDO suitable for always-on domains in automotive ECUs where the regulator sits on the battery-backed supply and the standby current budget is measured in tens of microamps. Texas Instruments lists this part as Active in production with ROHS3 compliance. ## PSRR: 53 dB at 1 kHz dropping to 30 dB at 1 MHz Power-supply rejection ratio is specified as 53 dB at 1 kHz, rolling off to 30 dB at 1 MHz. This profile means the LDO attenuates low-frequency ripple (e.g., 100/120 Hz from a rectified input) by a factor of ~450×, but switching noise above 100 kHz from a DC-DC converter passes through with only about 30 dB of rejection — a 100 mVpp switching ripple on the input appears as roughly 3 mVpp on the output. For noise-sensitive analog loads (sensor bias, ADC reference), an additional LC filter ahead of the LDO or a post-filter at the output may be needed if the upstream switcher operates above 500 kHz. ## 6-WSON (2x2 mm) with exposed pad — thermal and footprint The 1A output at 465 mV dropout dissipates up to 465 mW — without the exposed pad soldered to a copper island, the junction temperature rise above ambient can exceed the 125°C limit in a still-air environment. The 0.50 mm pitch and small footprint suit space-constrained automotive modules (camera ECUs, BMS sensor boards, gateway nodes).","metaTitle":"TI TPS74612PQWDRVRQ1 LDO Regulator, 1.2V Fixed, 1A, AEC-Q100","metaDescription":"Texas Instruments TPS74612PQWDRVRQ1 LDO, 1.2V fixed output, 1A, AEC-Q100 automotive grade.
