Minimum cathode current is 700 µA — below that the reference may not regulate; the design should always pull at least that much through the cathode to keep the bandgap active.","metaTitle":"TL431BIDE4 Adjustable Shunt Voltage Reference","metaDescription":"Texas Instruments TL431BIDE4 adjustable shunt voltage reference in 8-SOIC. ±0.5% tolerance, 100 mA output, -40°C to 85°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Tolerance":"±0.5%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"700 µA","Base Product Number":"TL431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~85°C(TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"8-SOIC","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431BIDE4/alternatives.json"},"ai":{"faq":[{"question":"What is the exact tolerance of TL431BIDE4?","answer":"The initial tolerance is ±0.5%, which is the B-grade selection from the TL431 family.
