It comes in a 6-WSON package with an exposed pad for thermal transfer to the PCB ground plane. The part includes enable control and built-in over-current and over-temperature protection — the basics you need for a supervised power rail in an ECU or sensor module. ## PSRR profile — where it helps and where it doesn't PSRR is specified at 53 dB at 1 kHz, dropping to 30 dB at 1 MHz. That means the part attenuates low-frequency ripple — alternator whine or switching-regulator ripple in the tens to hundreds of kHz — effectively. Above 1 MHz the rejection rolls off, so a post-filter or a separate LDO with higher high-frequency PSRR may be needed if the rail feeds a sensitive RF or high-speed digital load. ## Package and footprint for the board The 6-WSON with exposed pad (supplier device package 6-WSON 2x2 mm) is a hand-solderable SMD package. The exposed pad must be connected to the ground plane for thermal relief. ## Lifecycle and sourcing posture No end-of-life notice or last-time-buy window is in effect. For a BOM line needing an automotive-grade LDO, this part is a straightforward fit.","metaTitle":"TPS74628PQWDRVRQ1 Automotive LDO, 2.8V 1A, AEC-Q100, 6-WSON","metaDescription":"TI TPS74628PQWDRVRQ1 is an AEC-Q100 qualified 2.8V fixed-output LDO rated for 1A with 36 µA quiescent current and 195 mV max dropout.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"53dB ~ 30dB (1kHz ~ 1MHz)","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-WDFN Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"1A","Protection Features":"Over Current, Over Temperature","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C (TJ)","Voltage - Input (Max)":"6V","Voltage Dropout (Max)":"0.195V @ 1A","Supplier Device Package":"6-WSON (2x2)","Current - Quiescent (Iq)":"36 µA","Voltage - Output (Min/Fixed)":"2.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.53","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.53000","currency":"USD"},{"qty":10,"price":"$1.36600","currency":"USD"},{"qty":25,"price":"$1.29720","currency":"USD"},{"qty":100,"price":"$1.06540","currency":"USD"},{"qty":250,"price":"$0.99592","currency":"USD"},{"qty":500,"price":"$0.88012","currency":"USD"},{"qty":1000,"price":"$0.69483","currency":"USD"},{"qty":3000,"price":"$0.65550","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f92dc387e2ad3cb408b84d5d0a2cea48.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is TPS74628PQWDRVRQ1 automotive qualified?","answer":"Yes, it is part of TI's Automotive, AEC-Q100 series, qualified for automotive applications across the -40°C to 125°C junction temperature range."},{"question":"What is TPS74628PQWDRVRQ1's listed PSRR?","answer":"PSRR is specified as 53 dB at 1 kHz and 30 dB at 1 MHz.
