TL432M-A from Foshan Blue Rocket Elec, 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 | R | input | Reference input of the adjustable shunt regulator, where the internal reference is set to 1.240V typical (1.234V to 1.246V for the 0.5% grade, 1.228V to 1.252V for the 1% grade). |
| 2 | K | passive | Cathode of the shunt regulator, rated for a continuous cathode voltage of 20V maximum and a continuous cathode current range of -100 to +100 mA. |
| 3 | A | passive | Anode of the shunt regulator; the datasheet gives no separate electrical limit for this pin beyond the absolute maximum ratings and the test circuits. |
