TL432QPK from Texas Instruments, in a SOT-89-3. 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 | CATHODE | bidirectional | Shunt current/voltage input (cathode) that must be held within 36 V (absolute maximum 37 V referenced to ANODE) and driven with a cathode current of 1 mA to 100 mA. |
| 2 | ANODE | output | Common pin, normally grounded, to which all voltage ratings are referenced; on the SOT-89 it is also the tab attached to the substrate, so it must be connected to ANODE or left open. |
| 3 | REF | input | Reference input that the internal 2.5 V reference drives to; it must not be left floating, requires IREF of at least 4 µA, and its input current is limited to an absolute range of -0.05 mA to 10 mA. |
