It sets a reference voltage from 2.495 V up to 36 V using two external resistors, with a guaranteed initial tolerance of ±0.5% — tighter than the typical 1% grade of the standard TL431. The part sinks up to 100 mA and requires a minimum cathode current of 700 µA for regulation. ## Pin-compatible replacement path The TL432BQDBVR uses the SOT-23-5 footprint (also designated SC-74A / SOT-753). The TL432 family shares the same pinout and functional diagram with the TL431, which is widely available in the same SOT-23-5 package. If the ±0.5% tolerance is not strictly required, a TL431 variant with 1% tolerance in SOT-23-5 may serve as a drop-in replacement — confirm the cathode current and output drive match the application. No official TI cross-reference document is cited, so bench verification of the reference voltage and loop stability is recommended before committing a production run.","metaTitle":"TL432BQDBVR Adjustable Shunt Reference, ±0.5%, SOT-23-5","metaDescription":"TL432BQDBVR is an obsolete adjustable shunt voltage reference from the TL432 family. ±0.5% tolerance, 100 mA output, 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); Cut Tape (CT)","Tolerance":"±0.5%","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":"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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/99b53f28cf28b982a16c2a9ac87cd6e9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL432BQDBVR/alternatives.json"},"ai":{"faq":[{"question":"Is TL432BQDBVR obsolete?","answer":"Yes, Texas Instruments lists the TL432BQDBVR as obsolete.
