It operates as a shunt regulator, sinking current through the cathode to maintain the reference voltage across the output and anode terminals. The ±0.5% tolerance suits precision voltage regulation in feedback loops. ## Industrial temperature grade and 100 mA drive The shunt can sink up to 100 mA continuous cathode current, enough to drive an optocoupler LED in a feedback loop or bias a small load. Minimum cathode current is 700 µA, so the part stays in regulation even at light load. ## SOT-23-5 package — footprint and fit Sourcing is limited to surplus inventory and broker channels. For new designs, consider the TL431 family in SOT-23-5 as a functional alternative — note the pinout differs, so a PCB respin may be required.","metaTitle":"TL432BQDBVT Shunt Voltage Reference, 2.495V ±0.5%, SOT-23-5","metaDescription":"Texas Instruments TL432BQDBVT adjustable shunt voltage reference, 2.495V min, ±0.5% tolerance, 100 mA output, SOT-23-5, -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":"±0.5%","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":"700 µA","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/TL432BQDBVT/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy TL432BQDBVT and get a price?","answer":"The TL432BQDBVT is obsolete and sourced through independent distribution."},{"question":"TL432BQDBVT vs TL431 — what is the difference?","answer":"The TL432BQDBVT offers a tighter ±0.5% tolerance compared to the standard TL431's 1%.
