The SOT-89-3 (TO-243AA) surface-mount package suits compact power supply and control loops where board space is tight. ## Output range and cathode current — the operating window The shunt can sink up to 100 mA continuous, with a minimum cathode current of 700 µA to maintain regulation. The 2.495 V minimum output sets the floor; the 36 V maximum output covers most common rail voltages from 3.3 V to 24 V systems.","metaTitle":"TL431AQPKG3 Shunt Reference, ±1%, Adjustable, SOT-89-3","metaDescription":"TL431AQPKG3 adjustable shunt voltage reference, ±1% tolerance, 100 mA output, 2.495 V to 36 V range, SOT-89-3 package, -40°C to 125°C.","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":"±1%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-243AA","Product Status":"Active","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~125°C(TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"SOT-89-3","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431AQPKG3/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL431AQPKG3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL431AQPKG3 when reusing this data.
