TL432AIDBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection; pin 1 is not connected to the die and may be left floating. |
| 2 | ANODE | power_in | Common anode pin of the device; per the pin-function table this is the common return terminal, typically connected to circuit ground. |
| 3 | NC | unconnected | No internal connection; pin 3 is not connected to the die and may be left floating. |
| 4 | CATHODE | bidirectional | Shunt-regulator cathode/output terminal (parallel current/voltage input per pin table); sinks a regulated current of 1 mA to 100 mA (recommended operating range) while the cathode voltage is programmable from Vref (~2.5 V) up to 36 V (absolute max cathode voltage 37 V, absolute max continuous cathode current −100 mA to 150 mA); a minimum regulating current Imin of 0.4 mA typ 1 mA is required to keep the device in its linear region. |
| 5 | REF | input | Reference/threshold input measured relative to the common ANODE pin; the internal reference voltage Vref is nominally 2495 mV (2440-2550 mV range) when the device is biased, and the pin requires a reference input current Iref of at least 2 µA (typ 4 µA, max per grade) since it drives the base of an internal NPN. |
