For higher loads, the reference drives an external pass transistor. The 80 µA minimum cathode current defines the bias resistor value: R_bias = (V_in - V_ref) / I_bias, where I_bias must exceed 80 µA to keep the reference in regulation. At 80 µA quiescent, the reference adds negligible power dissipation in battery-powered or energy-harvesting nodes — the bias resistor dominates the loss.","metaTitle":"TLV431AIDBVRG4 Adjustable Shunt Voltage Reference, ±1%","metaDescription":"Texas Instruments TLV431AIDBVRG4 adjustable shunt voltage reference. ±1% tolerance, 1.24V min output, 15 mA output, SOT-23-5.","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":"±1%","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":"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/TLV431AIDBVRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TLV431AIDBVRG4 and TL431AIDBVR?","answer":"The TLV431AIDBVRG4 is the low-voltage variant of the TL431 family.
