LM4040DELT-2.0 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 | K | passive | Cathode of the shunt reference, where the 2.048 V reverse breakdown voltage appears; operating current is 10 µA minimum to 15 mA maximum. |
| 2 | A | passive | Anode of the shunt reference, connected to circuit ground. |
| 3 | NC | unconnected | No connect; must be left unconnected or connected to anode. |
