TL432C from PJSEMI, in a SOT-23. 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 | REF | input | Reference input of the shunt regulator, sensing the divider voltage against the 1.24V internal reference (IREF max 10mA absolute maximum). |
| 2 | CATHODE | passive | Cathode (K) of the shunt regulator, operating from VREF up to 18V with 0.1mA to 100mA cathode current (absolute max VKA 20V). |
| 3 | ANODE | power_in | Anode (A) of the shunt regulator, normally connected to ground. |
