TS4040DILT-2.5 from STMicroelectronics, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Cathode | passive | Cathode terminal of the shunt voltage reference; reverse breakdown voltage (Vk) is developed at this pin relative to the anode, nominally 2.5V at Ik=100µA. |
| 2 | Anode | passive | Anode terminal of the shunt voltage reference, typically connected to ground/return of the current-setting resistor circuit. |
| 3 | NC | unconnected | This pin must be left floating or connected to pin 2 (Anode). |
