With a ±1.5% tolerance, it holds the setpoint tighter than the standard ±2% grade, which matters when the regulation window is tight — think power-supply feedback dividers or comparator thresholds in industrial control loops. ## Drive capability and bias current The device can sink up to 15 mA of output current, which is enough to drive the optocoupler LED in a flyback supply or pull down a bias resistor network. The minimum cathode current is 80 µA — below that the reference stops regulating, so the bias resistor must be sized to keep at least 80 µA flowing through the device at all times. Housed in a SOT-23-5 (SC-74A compatible) package, this is a five-pin surface-mount part with a 0.95 mm pitch — straightforward for hand assembly or rework with a fine-tip iron. ## Obsolete — sourcing path and replacement The closest functional alternative in the same family is the TLV431A series (e.g., TLV431AIDBZR), which shares the same 1.24V reference and SOT-23-5 footprint but carries a tighter ±1% tolerance — verify the pinout and compensation before swapping. ## Sourcing this line item Because the part is obsolete, new stock moves through independent distribution and surplus channels. No stock-holding claim; each lot is verified against the original TI specification before shipment.","metaTitle":"TLV431IDBVTE4 adjustable shunt reference, 1.24V-6V, SOT-23-5","metaDescription":"Texas Instruments TLV431IDBVTE4 low-voltage adjustable shunt reference, 1.24V to 6V output, ±1.5% tolerance, 15 mA output, 80 µA cathode, SOT-23-5.","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":"±1.5%","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":"15 mA","Current - Supply":"-","Current - Cathode":"80 µA","Base Product Number":"TLV431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~85°C(TA)","Voltage - Output (Max)":"6 V","Supplier Device Package":"SOT-23-5","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"1.24V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4de43c4ff3ead6fd17ae3f61f4aa48c4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TLV431IDBVTE4/alternatives.json"},"ai":{"faq":[{"question":"How can I order TLV431IDBVTE4 or check current stock?","answer":"Submit an RFQ through this listing.
