The adjustable output goes up to 36 V, and the shunt can sink 100 mA continuous, which covers most low-power reference and error-amplifier loads. Cathode current requirement is 700 µA minimum, so the bias resistor must be sized to keep at least that flowing at the lowest input voltage.","metaTitle":"TL431AID Adjustable Shunt Reference, ±1%, 8-SOIC, Obsolete","metaDescription":"TL431AID adjustable shunt voltage reference, ±1% tolerance, 2.495V min output, 100 mA output, 8-SOIC package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"STMicroelectronics","Series":"-","Package":"Tube","Tolerance":"±1%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","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":"TL431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~105°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":"$0.4400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d3856169bdff63c55d41eeae5a91cadc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431AID/alternatives.json"},"ai":{"faq":[{"question":"Is TL431AID equivalent to TL431A?","answer":"The TL431AID is a specific variant of the TL431 family with ±1% tolerance in an 8-SOIC package.
