The ±0.5% tolerance is a BOM-fit differentiator: it tightens the reference accuracy over the standard 1% TLV431 grade, reducing the worst-case voltage error in ADC reference or comparator threshold circuits. The adjustable output spans 1.24 V (the internal bandgap) up to 6 V, set by two external resistors in the classic shunt configuration. For a 3.3 V rail, the feedback divider ratio lands near 1.66:1, well within the cathode current compliance. The SOT-23-5 footprint is shared with the broader TLV431 family, so a drop-in replacement for the standard-grade version is straightforward if tolerance requirements relax.","metaTitle":"TLV431BIDBVTE4 Shunt Voltage Reference, ±0.5%","metaDescription":"Texas Instruments TLV431BIDBVTE4 adjustable shunt reference, ±0.5% tolerance, 1.24 V to 6 V output, SOT-23-5, -40°C to 85°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)","Tolerance":"±0.5%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"100 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/TLV431BIDBVTE4/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of TLV431BIDBVTE4?","answer":"The TLV431BIDBVTE4 has a ±0.5% initial tolerance, tighter than the standard 1% grade."},{"question":"Is TLV431BIDBVTE4 pin compatible with TL431?","answer":"The TLV431BIDBVTE4 uses the same SOT-23-5 pinout as the standard TL431 in that package, so it is a direct footprint replacement. The key difference is the lower minimum cathode current (100 µA vs 1 mA for the TL431), which matters for low-power designs where the bias current budget is tight."},{"question":"What is the minimum cathode current for TLV431BIDBVTE4?","answer":"The minimum cathode current is 100 µA, significantly lower than the 1 mA typical for the standard TL431, enabling use in micropower bias circuits."},{"question":"How does TLV431BIDBVTE4 compare to TL431?","answer":"The TLV431BIDBVTE4 is a low-voltage variant of the TL431 family.
