It operates as a shunt reference with a programmable output from 1.24 V up to 6 V, set by two external resistors. The B-grade suffix selects the tighter ±0.5% initial tolerance bin, which is the primary spec that determines voltage accuracy in the application. ## Output drive and cathode bias headroom Rated for 15 mA continuous output current and a minimum cathode current of 100 µA, this part covers the typical biasing range for a shunt reference in a switching power supply feedback divider or an adjustable linear regulator. The 100 µA cathode floor sets the minimum bias resistor value for a given supply rail — below that the reference drops out of regulation. ## SOT-23-3 footprint and tape-and-reel delivery","metaTitle":"TLV431BCDBZRG4 Shunt Reference, ±0.5%, SOT-23-3","metaDescription":"Texas Instruments TLV431BCDBZRG4 adjustable shunt voltage reference. ±0.5% tolerance, 15 mA output, SOT-23-3.","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":"TO-236-3, SC-59, SOT-23-3","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":"0°C~70°C(TA)","Voltage - Output (Max)":"6 V","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"1.24V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4de43c4ff3ead6fd17ae3f61f4aa48c4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TLV431BCDBZRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the accuracy of TLV431BCDBZRG4?","answer":"The initial tolerance is ±0.5%, which is the B-grade bin of the TLV431 family.
