It provides an adjustable output from a 1.24V minimum up to 6 V maximum, with a reference tolerance of ±1.5%. This part is a lower-voltage variant of the industry-standard TL431 family, designed for applications where the reference voltage must go below the TL431's 2.5 V threshold. Typical uses include precision voltage monitoring, linear regulation post-regulation, and adjustable power supplies in commercial equipment. ## Output current and quiescent budget The shunt regulator can sink up to 15 mA of output current, which sets the maximum load the device can regulate. The cathode current minimum of 80 µA determines the bias resistor value needed to keep the device in regulation — a key parameter for low-power designs where every microamp matters. For a typical 3.3 V rail generation from a 5 V supply, the bias resistor is calculated as (Vin - Vout) / (Iload + Ikamin), where Ikamin is 80 µA. The 15 mA output ceiling means this part suits low-current auxiliary rails, not main power stages. ## Temperature grade and deployment scope It is not specified for industrial or automotive temperature extremes.","metaTitle":"TLV431CDBVT Adjustable Shunt Regulator, ±1.5% Tolerance","metaDescription":"Texas Instruments TLV431CDBVT low-voltage adjustable shunt regulator. 1.24V ref, 15 mA output, ±1.5% tolerance, SOT-23-5, 0°C to 70°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":"±1.5%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Active","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":"0°C~70°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":"$1.1800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4de43c4ff3ead6fd17ae3f61f4aa48c4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TLV431CDBVT/alternatives.json"},"ai":{"faq":[{"question":"Can TLV431CDBVT replace TL431?","answer":"The TLV431 is a lower-voltage variant of the TL431 family.
