It delivers a fixed 5V output at 2.5A continuous from an input range of 3.9V to 36V. The 3.9V minimum input covers a deeply discharged automotive battery during cold-crank; the 36V maximum handles load-dump transients without an external clamp, provided the upstream TVS is sized for the energy. Switching at 2.1 MHz, the regulator uses a small inductor — typically 2.2 µH to 4.7 µH — which shrinks the PCB footprint, but the fast edges demand tight layout of the input loop and the SW node to keep radiated emissions within CISPR 25 Class 5 limits. ## Junction temperature range and synchronous rectification Output is fixed at 5V with positive polarity; the single output channel is configured as a step-down (buck) topology. ## Package and board-fit — 22-VQFN with wettable flank Housed in a 22-VQFN-HR package measuring 5 mm × 4 mm, the part uses a wettable flank terminal finish. This allows automated optical inspection (AOI) of the solder fillet on the side of the package — a requirement for automotive production lines that cannot rely on bottom-only X-ray inspection. The surface-mount package with wettable flank is specified for the Automotive, AEC-Q100 series, supporting the PPAP documentation package that tier-one ECU programs require. Available in Tape & Reel (TR) and Cut Tape (CT) formats for both high-volume pick-and-place and prototype builds.","metaTitle":"TI LM53625LQURNLRQ1 Buck Regulator, 5V 2.5A, AEC-Q100","metaDescription":"Texas Instruments LM53625LQURNLRQ1 automotive step-down regulator, fixed 5V output at 2.5A, 3.9-36V input, 2.1MHz switching, -40°C to 150°C, 22-VQFN.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"22-VFQFN","lifecycle_stage":"eol_hot","Current - Output":"2.5A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"2.1MHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"36V","Voltage - Input (Min)":"3.9V","Supplier Device Package":"22-VQFN-HR (5x4)","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.55","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.55000","currency":"USD"},{"qty":10,"price":"$4.98100","currency":"USD"},{"qty":25,"price":"$4.70880","currency":"USD"},{"qty":100,"price":"$4.08080","currency":"USD"},{"qty":250,"price":"$3.87152","currency":"USD"},{"qty":500,"price":"$3.47392","currency":"USD"},{"qty":1000,"price":"$2.92981","currency":"USD"},{"qty":3000,"price":"$2.78332","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/534fdf92a088ab6b2a29c1ac06c736f9.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM53625LQURNLRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM53625LQURNLRQ1 when reusing this data.
