The 15 mA output current capability handles dynamic loads like an ADC sample-and-hold without droop. If the board sees a motor drive cabinet, outdoor telecom enclosure, or engine bay, step up to the industrial-grade TLV431BIDBVR (-40°C to 125°C). The SOT-23-5 package is small enough for space-constrained PCBs and rework-friendly — a hot-air station at 300°C with a fine nozzle lifts it clean without lifting adjacent passives. For dual-sourcing, the industry-standard TL431 family is pin-compatible but check the tolerance grade — the TL431A offers ±1% as well, while the TL431B tightens to ±0.5%. The SOT-23-5 footprint matches the standard SC-74A land pattern, so no PCB change is needed if swapping between TLV431 and TL431 variants in the same package.","metaTitle":"TLV431ACDBVR Shunt Voltage Reference, ±1% Tolerance","metaDescription":"Texas Instruments TLV431ACDBVR adjustable shunt voltage reference, ±1% tolerance, 1.24V to 6V output, 80 µA cathode current, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±1%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"80 µA","Base Product Number":"TLV431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"0°C~70°C(TA)","Voltage - Output (Max)":"6 V","Supplier Device Package":"SOT-23-5","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"1.24V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4de43c4ff3ead6fd17ae3f61f4aa48c4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TLV431ACDBVR/alternatives.json"},"ai":{"faq":[{"question":"Is TLV431ACDBVR obsolete or end-of-life?","answer":"No — the TLV431ACDBVR is listed as active. Texas Instruments continues production with no announced end-of-life. The base product TLV431 is a mature, widely second-sourced family, so supply risk is low."},{"question":"What is the difference between TLV431ACDBVR and TL431?","answer":"Both are adjustable shunt references with the same 1.24 V reference and 6 V max output. The TLV431ACDBVR offers a lower minimum cathode current (80 µA vs 1 mA typical for the standard TL431), making it better for battery-powered designs. The TL431 family includes tighter tolerance grades (0.5%) and wider temperature options, but at higher quiescent draw."},{"question":"Can TLV431ACDBVR be used as a voltage reference for an ADC?","answer":"Yes, for 8-bit to 10-bit ADCs where the ±1% tolerance and 80 µA cathode current are adequate. The 15 mA output can drive the ADC reference input directly. For 12-bit or higher precision, consider the TLV431B with ±0.5% tolerance or a dedicated series reference like the REF3030."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLV431ACDBVR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLV431ACDBVR when reusing this data.
