The internal reference is 2.495 V minimum, the familiar TL43x anchor voltage that sets the divider ratio for any output up to 36 V. ## 15 mA cathode current — enough for most feedback loops Rated for 15 mA continuous output current with a 1 mA minimum cathode current to maintain regulation. That 1 mA floor sets the bias resistor ceiling: for a 12 V rail, a 10 kΩ bias resistor keeps the cathode current above threshold across the full load range. The 15 mA ceiling covers the typical optocoupler LED drive in an isolated flyback or a TL431-style feedback loop. The SOT-23-3 package keeps the footprint small enough for a dense PSU layout. ## Industrial temperature range — engine bay and factory floor No commercial-grade part needed for these environments; this one covers the full industrial envelope. The base product number is TL432, a long-running TI portfolio that shares the same pinout and basic function across the family.","metaTitle":"TL432LIBQDBZR Shunt Reference, ±0.5%, SOT-23-3","metaDescription":"Texas Instruments TL432LIBQDBZR adjustable shunt voltage reference, ±0.5% tolerance, 2.495 V min output, 36 V max, 15 mA output, -40°C to 125°C, SOT-23-3.","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":"±0.5%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","Reference Type":"Shunt","lifecycle_stage":"eol_hot","Current - Output":"15 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-23-3","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9234c39c5cbd1d015161df75db2c9943.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL432LIBQDBZR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TL432 and TL431?","answer":"The TL432 uses the same internal 2.495 V reference and adjustable shunt topology as the TL431, but the pinout is reversed — the TL432 swaps the reference and cathode pins.
