TP432C249T3 from TECH PUBLIC, 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 | passive | Cathode of the adjustable shunt regulator, rated to 36 V maximum cathode voltage with 1.0 to 100 mA continuous cathode current. |
| 2 | ANODE | passive | Anode of the shunt regulator, the reference for all voltage ratings, normally connected to ground. |
| 3 | REF | input | Reference input that sets the output voltage via an external divider, with a typical reference voltage of 2.495 V and a maximum reference input current of 10 mA. |
