This makes it the part to reach for when the feedback divider in a power supply or the reference in an ADC bias network cannot tolerate the wider spread of the commodity-grade shunt. Output is adjustable from a 1.24 V minimum up to 6 V maximum, set by two external resistors. The shunt regulates by sinking up to 15 mA through the cathode, with a minimum cathode current of 100 µA to maintain regulation. ## Industrial temperature range and SOT-23-3 footprint The SOT-23-3 package (TO-236-3 / SC-59) is a three-lead surface-mount footprint that fits into compact layouts alongside passives. The shunt reference type means it behaves as a three-terminal programmable Zener: the cathode sinks current to hold the reference pin at the programmed voltage. No external pass transistor is needed for loads up to 15 mA, which keeps the BOM count low.","metaTitle":"TLV431BIDBZRG4 precision shunt regulator, ±0.5% tolerance","metaDescription":"Texas Instruments TLV431BIDBZRG4 low-voltage adjustable shunt regulator. ±0.5% tolerance, 1.24 V to 6 V output, 15 mA cathode current, -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":"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":"-40°C~85°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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4de43c4ff3ead6fd17ae3f61f4aa48c4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TLV431BIDBZRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of TLV431BIDBZRG4?","answer":"The TLV431BIDBZRG4 is specified with a ±0.5% tolerance on the reference voltage."},{"question":"Can TLV431BIDBZRG4 replace the standard TL431?","answer":"Yes, it is pin-compatible with the standard TL431 in the SOT-23-3 footprint.
