The minimum cathode current is 600 µA, which sets the floor for the bias resistor in the shunt path — below that the reference loses regulation. ## SOT-23-5 package and tape-and-reel delivery Housed in a SOT-23-5 package (SC-74A, SOT-753), the part is suited for compact surface-mount layouts.","metaTitle":"TL431ACDBVRG4 Shunt Regulator, 2.495 V Ref, ±1%, SOT-23-5","metaDescription":"Texas Instruments TL431ACDBVRG4 adjustable shunt voltage reference, 2.495 V min output, ±1% tolerance, 100 mA output, SOT-23-5 package.","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)","Tolerance":"±1%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"600 µA","Base Product Number":"TL431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"0°C~70°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/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431ACDBVRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TL431ACDBVRG4 and TL431BCDBVRG4?","answer":"The primary difference is tolerance: TL431ACDBVRG4 is specified at ±1%, while the TL431BCDBVRG4 is specified at ±0.5% (per the TL431 family datasheet).
