The ±2.2% tolerance on the reference means your output voltage stays within that band over temperature and load, which is tight enough for most power-supply feedback loops and monitoring circuits without needing a precision-grade part. It's the lower-voltage sibling in the TL431 family, sharing the same basic topology but with a lower minimum cathode voltage. ## SOT-23-5: hand-solderable and board-friendly The part comes in a SOT-23-5 package (also listed as SC-74A). No hidden pads under the body, so inspection is straightforward. The supplier device package is SOT-23-5, and the case code is SC-74A, SOT-753 — they refer to the same physical footprint. Surface-mount only, no through-hole variant in this suffix. If you need a breadboard-friendly version, grab a SOIC-8 TL432 or a small adapter board for the SOT-23-5. ## 100 mA output and 1 mA cathode current — what they mean The 100 mA output current rating tells you the shunt can sink up to 100 mA while regulating. That's enough to drive an optocoupler LED in a feedback loop, bias a small load, or pull down a voltage divider. The 1 mA minimum cathode current is the minimum current you need to keep the device regulating — your bias resistor must deliver at least that much. Below 1 mA the reference may drop out of regulation. You can design it into new builds without worrying about a last-time-buy window closing. The base product number is TL432, so any future PCNs or datasheet updates will track under that family.","metaTitle":"TL432IDBVR Shunt Voltage Reference, 2.495V, ±2.2%, SOT-23-5","metaDescription":"Texas Instruments TL432IDBVR adjustable shunt voltage reference. 2.495V min output, ±2.2% tolerance, 100 mA output, SOT-23-5 package.

Both are adjustable shunt references, but the TL432 has a lower minimum cathode voltage (2.495V vs the TL431's 2.5V typical) and comes in a different pinout in the SOT-23-5 package. Check the pin assignments on your board — the TL432IDBVR uses the SOT-23-5 pinout, while the TL431 is more common in SOT-23-3 or TO-92. Functionally they are interchangeable in most feedback and monitoring circuits if the pinout matches."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL432IDBVR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL432IDBVR when reusing this data.
