Rated for 100 mA cathode current with a minimum cathode current of 600 µA, the device can sink enough current to drive optocoupler LEDs or bias a pass transistor in a linear regulator loop. ## ±1% tolerance and commercial temperature range The ±1% tolerance on the reference voltage gives tighter output regulation than the standard ±2% TL431 grade, which matters when the reference sets the feedback threshold in a 5 V or 3.3 V supply where every millivolt of error eats into the load-regulation budget. ## SOT-23-5 package and tape-and-reel delivery The Tape & Reel (TR) packaging is feeder-ready for pick-and-place lines — no tube-to-reel conversion needed. For BOM lines that still call out this exact code, procurement must source through independent distributors or the surplus market.","metaTitle":"TL431ACDBVTG4 Shunt Reference, ±1%, 100 mA, SOT-23-5","metaDescription":"Texas Instruments TL431ACDBVTG4 adjustable shunt voltage reference, ±1% tolerance, 100 mA cathode current, SOT-23-5 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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","Product Status":"Obsolete","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":"$0.4100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/99b53f28cf28b982a16c2a9ac87cd6e9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431ACDBVTG4/alternatives.json"},"ai":{"faq":[{"question":"Is the TL431ACDBVTG4 obsolete?","answer":"Yes, Texas Instruments lists the TL431ACDBVTG4 as Obsolete.
