The part sinks up to 100 mA of cathode current, making it suitable for series-pass regulator feedback loops, error amplifiers, and precision current-limiting circuits in power supplies and battery chargers. Texas Instruments no longer manufactures this specific ordering code in production volumes. Every unit we supply is traceable and inspected — we verify date-code consistency, marking legibility, and package integrity before it ships. ## Key ratings that determine fit The adjustable output spans 2.495V to 36V — the lower bound is the internal reference voltage, and the upper bound is set by the cathode-to-anode breakdown. The ±2.2% tolerance on the reference voltage is a standard precision grade: adequate for general-purpose regulation in switch-mode power supply feedback loops, but not tight enough for high-accuracy instrumentation references where ±0.5% or better is typical. If your design draws less than 1 mA through the cathode, the reference may not regulate cleanly — a common oversight when the shunt is biased through a high-value resistor. The SOT-23-5 footprint is a widely used industry standard for five-pin small-signal devices. The mounting type is surface mount, and the shipping medium is Tape & Reel (TR). The SOT-23-5 package is pin-compatible with many other adjustable shunt references in this footprint class, which matters if you are evaluating a second-source drop-in for a board already laid out for this code.","metaTitle":"TL432QDBVRG4 Adjustable Shunt Reference, SOT-23-5, Obsolete","metaDescription":"Texas Instruments TL432QDBVRG4 adjustable shunt voltage reference, 2.495V min / 36V max output, ±2.2% tolerance, 100 mA cathode current, -40°C to 125°C","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~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/TL432QDBVRG4/alternatives.json"},"ai":{"faq":[{"question":"Is TL432QDBVRG4 equivalent to TL431?","answer":"The TL432QDBVRG4 is functionally equivalent to the TL431 — both are adjustable shunt references with the same 2.495V internal reference and similar operating characteristics. The key difference is the package: the TL432 is offered in smaller surface-mount packages like SOT-23-5, while the TL431 is commonly available in larger TO-92, SOIC-8, and SOT-23-3 packages. The pinout differs between the two families, so they are not drop-in replacements without a PCB layout change."},{"question":"Where can I buy TL432QDBVRG4 in bulk?","answer":"The TL432QDBVRG4 can be sourced through independent distribution against an RFQ. Because the part is obsolete, bulk quantities are subject to available surplus and remaining factory inventory.
