Any stock available today is from the last production lots or surplus inventory. For a production BOM, this part is a single-source risk — you need a qualified replacement before the remaining stock dries up. ## Adjustable shunt reference with ±0.5% tolerance The output is set with two external resistors to any voltage between 2.495 V and 36 V. The ±0.5% tolerance on the internal reference means the set-point accuracy is tight enough for a precision power supply or an ADC reference — no trim pot needed for most designs. That 100 mA ceiling covers biasing an op-amp chain, driving a small LED load, or powering a low-dropout post-regulator. The 700 µA floor means the external resistor divider must sink at least that much current to keep the reference in its linear region. ## Industrial temperature grade in a SOT-23-5 footprint The SOT-23-5 package (SC-74A, SOT-753) is a five-pin variant of the common SOT-23 footprint. The extra pin is a separate anode connection; the cathode and reference pins match the TL431 pinout, so the board layout transfers if you swap between the two families. ## Sourcing reality for a discontinued part No official replacement order code is listed by Texas Instruments for this specific variant, so a cross-reference search or a pin-compatible alternate from the TL431/TL432 family is the next step for a production BOM.","metaTitle":"TL432BQDBVRE4 Shunt Reference, Adjustable, ±0.5%, SOT-23-5","metaDescription":"TL432BQDBVRE4 adjustable shunt voltage reference, ±0.5% tolerance, 100 mA output, SOT-23-5.
