It is qualified to AEC-Q100, making it suitable for automotive power-management applications including ECU supply rails, sensor bias, and ADAS module local regulation. The device integrates enable and reset control features, plus protection against over-current, over-temperature, and reverse polarity. ## Dropout and quiescent current — what they mean for the 5V rail Maximum dropout voltage is 0.38V at 1A output. With a 5V output, the input must stay above about 5.4V to maintain regulation at full load — a margin that matters during automotive cold-crank events where the battery bus can sag below 6V. Quiescent current is 125 µA, a reasonable figure for a 1A LDO; it keeps the load on the always-on battery line modest when the system is in standby but the regulator stays enabled. PSRR is specified at 60dB at 1kHz. This gives about 1 mV ripple rejection per volt of input ripple at that frequency, which is adequate for cleaning up a switching pre-regulator feeding a 5V analog or logic rail in an automotive module. ## Package and temperature range for under-hood deployment The device is offered in a 20-pin HTSSOP (PowerTSSOP) package with an exposed thermal pad. The operating temperature range is -40°C to 125°C, covering the full automotive under-hood and cabin environment. Surface-mount assembly is standard; the thermal pad should be soldered to a PCB copper plane for adequate heat dissipation at 1A continuous load. ## Lifecycle and sourcing — active production, no LTB risk The TPS76750QPWPRQ1 is listed as Active in production status.","metaTitle":"TPS76750QPWPRQ1 LDO Regulator, 5V Fixed Output, 1A, AEC-Q100","metaDescription":"TI TPS76750QPWPRQ1 automotive LDO: 5V fixed output, 1A, 125 µA quiescent, 60dB PSRR at 1kHz, AEC-Q100, 20-HTSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"PSRR":"60dB (1kHz)","Grade":"Automotive","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Package / Case":"20-PowerTSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Control Features":"Enable, Reset","Current - Output":"1A","Protection Features":"Over Current, Over Temperature, Reverse Polarity","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C","Voltage - Input (Max)":"10V","Voltage Dropout (Max)":"0.38V @ 1A","Supplier Device Package":"20-HTSSOP","Current - Quiescent (Iq)":"125 µA","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.78","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.78000","currency":"USD"},{"qty":10,"price":"$4.29300","currency":"USD"},{"qty":25,"price":"$4.05880","currency":"USD"},{"qty":100,"price":"$3.51750","currency":"USD"},{"qty":250,"price":"$3.33716","currency":"USD"},{"qty":500,"price":"$2.99440","currency":"USD"},{"qty":1000,"price":"$2.52540","currency":"USD"},{"qty":2000,"price":"$2.39914","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a9d650e76b4072e3fff48c4af6c2a8d5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is TPS76750QPWPRQ1 AEC-Q100 qualified?","answer":"Yes, the TPS76750QPWPRQ1 is AEC-Q100 qualified, confirming its suitability for automotive-grade applications."},{"question":"What is the difference between TPS76750QPWPRQ1 and TPS76750QPWP?","answer":"The TPS76750QPWPRQ1 is the tape-and-reel (TR) ordering option of the same device; the TPS76750QPWP is the tube/tray variant.
