The 40 V maximum input covers a 12 V battery's full transient range — cold-crank dips and load-dump spikes both stay inside the abs-max envelope without an external clamp. Maximum dropout is 0.575 V at the full 500 mA load, so a 5.575 V input rail is the floor for regulation at rated current. The 26 µA quiescent current keeps the draw negligible in always-on ECU domains. AEC-Q100 Grade 0 qualification means the junction temperature range spans -40°C to 150°C — this is the engine-bay band. An exhaust-adjacent module or transmission controller that sees 125°C ambient still has 25°C of margin before the thermal shutdown threshold. ## PSRR and protection — what the 70 dB figure buys you PSRR is 70 dB at 1 kHz — that attenuates a 100 mV ripple on the input rail to roughly 30 µV at the output. Above the crossover frequency the rejection rolls off, so a switching pre-regulator running at 400 kHz needs its output capacitor to handle the high-frequency attenuation before the LDO. Integrated protection covers over-current, over-temperature, and under-voltage lockout. The Power Good flag asserts when the output is within regulation — a pull-up resistor to the output rail lets the downstream ECU monitor the rail status without an additional comparator. ## TO-252-5 DPak — board integration The TO-252-5 (DPak) package has four leads plus a tab — the tab is the thermal pad and is tied to ground.","metaTitle":"TPS7B8750QKVURQ1R2 LDO, 500mA, 40V, AEC-Q100, TO-252-5","metaDescription":"Texas Instruments TPS7B8750QKVURQ1R2 automotive LDO regulator, 500mA output, 40V input, 70dB PSRR at 1kHz, AEC-Q100 qualified.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"PSRR":"70dB (1kHz)","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-252-5, DPak (4 Leads + Tab), TO-252AD","lifecycle_stage":"eol_hot","Control Features":"Power Good","Current - Output":"500mA","Protection Features":"Over Current, Over Temperature, Under Voltage Lockout (UVLO)","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 150°C (TJ)","Voltage - Input (Max)":"40V","Voltage Dropout (Max)":"0.575V @ 500mA","Supplier Device Package":"TO-252-5","Current - Quiescent (Iq)":"26 µA","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.76","priceTiers":[{"qty":1,"price":"$2.95000","currency":"USD"},{"qty":10,"price":"$2.65200","currency":"USD"},{"qty":25,"price":"$2.50160","currency":"USD"},{"qty":100,"price":"$2.13140","currency":"USD"},{"qty":250,"price":"$2.00128","currency":"USD"},{"qty":500,"price":"$1.75112","currency":"USD"},{"qty":1000,"price":"$1.45093","currency":"USD"},{"qty":2500,"price":"$1.41600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/99bdf54be267f0a29355f32d35ffb604.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS7B8750QKVURQ1R2/alternatives.json"},"ai":{"faq":[{"question":"What is the PSRR of this LDO at 1 kHz?","answer":"The TPS7B8750QKVURQ1R2 provides 70 dB of power supply rejection at 1 kHz.
