LM4040DIM3-10 from HGSEMI, in a SOT-23. 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 | V+ | passive | Positive (cathode) terminal of the shunt reference. Connect through a series resistor Rs to the supply Vs to establish the 10 V reference; sink current range 100 µA to 15 mA. Absolute max reverse current 20 mA. |
| 2 | V- | passive | Negative (anode) terminal of the shunt reference; system ground reference for the 10 V output. |
| 3 | NC | unconnected | No internal connection. Per the datasheet, pin 3 must be left floating or connected to pin 2 (V-). Do not tie to any other node. |
