Output tolerance is ±2.2%, which is tighter than the standard ±1% grade of some peers — useful for precision feedback loops in power supplies and battery chargers where the setpoint error directly affects regulation accuracy. ## 100 mA cathode current — load-driving capability The device can sink up to 100 mA of cathode current, which covers most shunt-reference loads in offline flyback converters, linear regulators, and isolated DC-DC feedback paths. Below that threshold the reference drops out of regulation. It is not qualified for automotive under-hood environments (no AEC-Q100 grade).","metaTitle":"TL432IDBVRE4 Shunt Reference, Adjustable 2.495V–36V","metaDescription":"TL432IDBVRE4 adjustable shunt reference, 2.495V min output, 100 mA cathode current, ±2.2% tolerance, -40°C to 85°C, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±2.2%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"1 mA","Base Product Number":"TL432","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~85°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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/99b53f28cf28b982a16c2a9ac87cd6e9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL432IDBVRE4/alternatives.json"},"ai":{"faq":[{"question":"Is TL432IDBVRE4 compatible with TL431?","answer":"The TL432 is functionally identical to the TL431 — same adjustable shunt-reference architecture, same 2.495 V reference voltage, same 36 V maximum output. The main difference is package: the TL432IDBVRE4 comes in SOT-23-5, while the TL431 is commonly available in larger packages like SOIC-8 or TO-92. Pinout differs between packages, so they are not drop-in replacements without a layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL432IDBVRE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL432IDBVRE4 when reusing this data.
