It operates as a low-voltage counterpart to the industry-standard TL431, with a minimum cathode current of 100 µA and a maximum output current of 15 mA, making it suitable for precision regulation in battery-powered and portable equipment. The ±0.5% tolerance on the internal reference voltage (1.24 V min/fixed) gives tighter regulation than the standard TL431's ±1% or ±2% grades. For a 3.3 V rail set with a resistor divider, that translates to roughly ±16.5 mV worst-case at the output — enough to keep a 3.3 V logic supply inside spec without an external trim pot. The adjustable output range extends from 1.24 V up to 6 V. That 6 V ceiling limits this part to low-voltage rails — 5 V logic, 3.3 V, 1.8 V, or similar. The SOT-23-3 (TO-236-3, SC-59) is a three-lead surface-mount package with a 0.95 mm pin pitch. It reflows cleanly with a standard hot-air station at 260°C peak — no thermal pad underneath, so the part lifts easily without cooking the board. The small body (2.9 mm × 1.3 mm) saves board area but means the junction-to-ambient thermal resistance is higher than a larger SOT-223 — keep the copper pad area generous under the anode connection if dissipating more than a few milliwatts.","metaTitle":"TLV431BCDBZTG4 Shunt Voltage Reference, ±0.5%, SOT-23-3","metaDescription":"Texas Instruments TLV431BCDBZTG4 adjustable shunt 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":"$35.9200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4de43c4ff3ead6fd17ae3f61f4aa48c4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TLV431BCDBZTG4/alternatives.json"},"ai":{"faq":[{"question":"Can TLV431BCDBZTG4 replace TL431?","answer":"The TLV431BCDBZTG4 is a low-voltage variant of the TL431 family. It is pin-compatible with the TL431 in the SOT-23-3 package, but its maximum output voltage is 6 V versus the TL431's 36 V. For rails up to 6 V, it is a drop-in replacement with tighter ±0.5% tolerance. For higher-voltage rails, stick with the TL431."},{"question":"What is the difference between TLV431BCDBZTG4 and TL431?","answer":"The key difference is the maximum output voltage: the TLV431BCDBZTG4 is rated for 6 V maximum, while the TL431 handles up to 36 V. The TLV431BCDBZTG4 also offers a tighter ±0.5% tolerance compared to the standard TL431's ±1% or ±2% grades. Both are adjustable shunt references, but the TLV431 is optimised for low-voltage precision applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLV431BCDBZTG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLV431BCDBZTG4 when reusing this data.
