The ±1% tolerance on the reference voltage suits precision power supply feedback loops, isolated DC-DC secondary-side regulation, and voltage monitoring circuits where tighter than the standard ±2% grade is needed without moving to a 0.5% device. ## Output current and cathode current — sizing the bias resistor Rated for 100 mA continuous output current, the TL432AQDBVR can sink enough current to drive the optocoupler LED in a feedback loop or pull down a pull-up resistor in a window comparator. For a typical 5 V rail feeding the cathode through a 1 kΩ resistor, the bias current lands around 4.3 mA — well above the 700 µA minimum and leaving headroom for the optocoupler current. The SOT-23-5 package (SC-74A, SOT-753) is a 5-pin surface-mount footprint with 0.95 mm pitch — standard for small-signal placement on dense PCBs.","metaTitle":"TL432AQDBVR Shunt Regulator, Adjustable, ±1%, SOT-23-5","metaDescription":"TL432AQDBVR adjustable shunt voltage reference, ±1% tolerance, 100 mA output, -40°C to 125°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); Cut Tape (CT)","Tolerance":"±1%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Active","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":"$0.1495","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL432AQDBVR/alternatives.json"},"ai":{"faq":[{"question":"Is TL432AQDBVR equivalent to TL431 and can it replace TL431 directly?","answer":"The TL432 is functionally equivalent to the TL431 — same 2.495 V reference, same adjustable output to 36 V, same ±1% tolerance option. The difference is the pinout: the TL432 swaps the REF and CATHODE pins relative to the TL431. On a TL431 layout the REF pin is typically pin 1 and CATHODE is pin 3; on the TL432AQDBVR in SOT-23-5 the REF is pin 3 and CATHODE is pin 1. A direct drop-in replacement requires a board spin or a cross-over pattern; it is not pin-compatible without a layout change."},{"question":"What is the tolerance of TL432AQDBVR?","answer":"The TL432AQDBVR is specified with ±1% tolerance on the reference voltage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL432AQDBVR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL432AQDBVR when reusing this data.
