The output is adjustable from 1.2 V up to 18 V, delivering up to 500 mA. Quiescent current is 26 µA typical, which keeps the standing load on the battery low in always-on ECU modules. ## AEC-Q100 and 150°C junction — deployment in under-hood and engine-bay environments The AEC-Q100 qualification and the 150°C maximum junction temperature together mean this part is rated for the thermal and reliability demands of automotive under-hood and engine-bay modules — ECU, transmission control, sensor power supplies, and CAN transceiver rails. The 40 V input rating handles the 36 V load-dump clamp typical in 12 V systems, and the 500 mA output is enough to power a small microcontroller plus a few peripheral loads. The TO-252-5 package with its exposed pad needs a good thermal via stitch to the ground plane to keep the junction below 150°C at full load in a hot environment. ## 70 dB PSRR at 1 kHz — clean rail for noise-sensitive loads The 70 dB power-supply rejection ratio at 1 kHz is strong for a 500 mA LDO. It means the output stays clean even when the input bus carries ripple from an alternator or a switching pre-regulator. This matters for analog sensor supplies, audio codec rails, and CAN transceiver VCC where conducted noise on the 12 V bus would otherwise couple into the signal path. The dropout voltage is 0.570 V maximum at 500 mA, so a 5 V input can hold a 3.3 V rail through cold-crank conditions down to about 3.9 V input. ## Control and protection features — built-in supervision The part integrates current limit, over-temperature shutdown, and under-voltage lockout (UVLO), plus a Power Good output and an Enable pin. The UVLO threshold prevents the regulator from trying to regulate below its minimum input voltage, which avoids erratic output behaviour during a slow battery ramp. The Enable pin lets a system supervisor or a sequencing controller turn the rail on and off without a separate load switch.","metaTitle":"TPS7B8601QKVURQ1 Automotive LDO, 40V Input, 500mA","metaDescription":"Texas Instruments TPS7B8601QKVURQ1 AEC-Q100 LDO regulator: 40V input max, 500mA output, adjustable 1.2V to 18V, 70dB PSRR at 1kHz, -40°C to 150°C junction","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"PSRR":"70dB (1kHz)","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-252-5, DPak (4 Leads + Tab), TO-252AD","lifecycle_stage":"eol_hot","Control Features":"Current Limit, Delay, Enable, 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)":"0.570V @ 500mA","Voltage - Output (Max)":"18V","Supplier Device Package":"TO-252-5","Current - Quiescent (Iq)":"26 µA","Voltage - Output (Min/Fixed)":"1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.64","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.77000","currency":"USD"},{"qty":10,"price":"$2.48600","currency":"USD"},{"qty":25,"price":"$2.34520","currency":"USD"},{"qty":100,"price":"$1.99820","currency":"USD"},{"qty":250,"price":"$1.87620","currency":"USD"},{"qty":500,"price":"$1.64168","currency":"USD"},{"qty":1000,"price":"$1.36024","currency":"USD"},{"qty":2500,"price":"$1.32750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d3fca0b7eec38a659121e3b27f391b00.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the PSRR of TPS7B8601QKVURQ1?","answer":"The power-supply rejection ratio is 70 dB at 1 kHz, which is typical for a 500 mA LDO in this class and sufficient to clean up ripple from a switching pre-regulator."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS7B8601QKVURQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS7B8601QKVURQ1 when reusing this data.
