TS3431ILT from STMicroelectronics, in a SOT-23-3L. 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 shunt regulator, which sinks 0.5 to 100 mA operating current at 1.24 to 24 V cathode voltage (25 V absolute maximum cathode to anode). |
| 2 | Reference | input | Reference input of the shunt regulator, connected to the external resistor bridge that sets the output voltage between 1.24 V and 24 V, with reference input current absolute maximum range of 0.05 to +10 mA. |
| 3 | Anode | passive | Anode of the shunt regulator, normally connected to ground, with reverse breakdown current range of -100 to +150 mA. |
