TL432BIPK from Texas Instruments, in a SOT-89-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CATHODE | bidirectional | Shunt regulator cathode node; sinks 1 mA to 100 mA (Imin=0.4 mA typ, abs-max continuous range −100 mA to 150 mA) to hold the programmed voltage, rated up to 37 V (abs max)/36 V (recommended) referenced to ANODE. |
| 2 | ANODE | output | Common/anode pin, normally tied to ground, providing the return path for the cathode current; on this SOT-89 (PK) package the metal mounting tab is internally tied to this same ANODE node. |
| 3 | REF | input | Reference input pin that must be biased with ≥ Iref (typ. 2 µA, max 4 µA) and is compared internally to the 2.495 V (typ) precision reference to control the cathode sink current; note TL432 swaps the REF and CATHODE pin positions relative to TL431. |
