The 2.495 V minimum output sets the floor for the adjustable range; the cathode can regulate up to 36 V, so it covers common 3.3 V, 5 V, 12 V, and 24 V rails. The 100 mA output current is the maximum the reference can sink — useful for driving an optocoupler LED or biasing a pass transistor in a linear regulator. The 1 mA minimum cathode current means the part needs at least that much bias to stay in regulation; a design with a light load must include a pull-up resistor to guarantee this current. ## Package and footprint — SOT-23-5 The SOT-23-5 (also listed as SC-74A) is a five-pin surface-mount package with 0.95 mm pitch — easily hand-soldered with a fine-tip iron or reflowed in a toaster oven. The pinout is standard for the TL432 family: cathode, anode, and reference.","metaTitle":"TL432QDBVTG4 Adjustable Shunt Reference, 2.495 V, SOT-23-5","metaDescription":"TL432QDBVTG4 adjustable shunt reference, 2.495 V min output, 100 mA cathode current, ±2.2% tolerance, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±2.2%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"1 mA","Base Product Number":"TL432","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~125°C(TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"SOT-23-5","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/99b53f28cf28b982a16c2a9ac87cd6e9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL432QDBVTG4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for TL432QDBVTG4?","answer":"Texas Instruments has not listed an official successor for the TL432QDBVTG4. A common functional alternative is the TL431 family in a similar package (e.g., TL431AIDBZR in SOT-23-3), but the pinout differs — the TL432 uses a different pin arrangement than the TL431. Verify the pinout against your PCB layout before substituting."},{"question":"Can TL432QDBVTG4 replace TL431?","answer":"The TL432 is functionally similar to the TL431 — same 2.495 V reference, same adjustable output up to 36 V, same 100 mA sink capability. However, the pinout is different: the TL432 has a different arrangement of cathode, anode, and reference pins. Check your board's footprint before swapping."},{"question":"What is the difference between TL432 and TL432Q?","answer":"The 'Q' in TL432QDBVTG4 typically indicates an automotive-qualified variant (AEC-Q100). The base electrical specs — 2.495 V reference, 100 mA output, adjustable output — are the same."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL432QDBVTG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL432QDBVTG4 when reusing this data.
