It is a three-terminal device — cathode, anode, and reference — that behaves like a low-temperature-coefficient Zener when the reference pin is tied to the output, or as a programmable shunt when a resistor divider sets the voltage up to 6 V. ## Industrial temperature range and output drive The shunt can sink up to 15 mA continuous, enough to bias an optocoupler in a flyback feedback loop or pull down a supervisory reset line.","metaTitle":"TLV431BQDBVR Shunt Voltage Reference, 1.24 V ±0.5%, SOT-23-5","metaDescription":"Texas Instruments TLV431BQDBVR adjustable shunt reference, 1.24 V min output, ±0.5% tolerance, -40°C to 125°C, 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":"±0.5%","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":"100 µA","Base Product Number":"TLV431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~125°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":"$0.8500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4de43c4ff3ead6fd17ae3f61f4aa48c4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TLV431BQDBVR/alternatives.json"},"ai":{"faq":[{"question":"Is TLV431BQDBVR an adjustable or fixed voltage reference?","answer":"Adjustable.
