TS3431BILT from STMicroelectronics, 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 | Cathode | output | Adjustable reference output voltage terminal with operating voltage range of 1.24 to 24 V and sink current capability of 0.4 to 100 mA. |
| 2 | Reference | input | Reference adjustment input terminal for external resistor divider network with input current of 0.9 to 1.5 µA at 25°C and maximum 2 µA across -40 to +125°C temperature range. |
| 3 | Anode | power_in | Anode return terminal for current path with maximum reverse breakdown current of 150 mA and cathode-to-anode operating voltage of 1.24 to 24 V. |
