The ±1% tolerance on the internal reference keeps the regulation tight across temperature, which matters when you are setting the feedback divider on a flyback converter or a linear regulator. ## 100 mA cathode current — sink capacity for the rail Rated for 100 mA continuous output current, the TL432AQDBVT can sink enough current to drive the optocoupler LED in an isolated power supply feedback loop or to bias a pass transistor. The SOT-23-5 package — also known as SC-74A — is a compact footprint that fits tight PCB layouts, but the small body means the power dissipation is limited; at 100 mA and a 5 V cathode-to-anode drop the die sees 500 mW, which exceeds the package's thermal capacity without a copper pour. For continuous high-current operation, budget a larger copper pad or a bigger package variant. For dual-sourcing flexibility, the TL432BIDBVT is a pin-compatible sibling with the same SOT-23-5 footprint and similar electrical characteristics; the main difference is the temperature grade, so confirm the operating range matches your application before substituting.","metaTitle":"TL432AQDBVT Shunt Regulator, Adjustable, ±1%, SOT-23-5","metaDescription":"Texas Instruments TL432AQDBVT shunt voltage reference, adjustable output from 2.495 V to 36 V, ±1% tolerance, 100 mA output, -40°C to 125°C, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"-","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Tolerance":"±1%","Output Type":"Adjustable","Part Status":"Active","Manufacturer":"Texas Instruments","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"700 µA","Base Product Number":"TL432","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C ~ 125°C (TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"SOT-23-5","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/50087f9afff55d28d5567f1ecd42327f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL432AQDBVT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL432AQDBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL432AQDBVT when reusing this data.
