LM4040CEM3-3.0+T from Analog Devices Inc Maxim Integrated, 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 | + | passive | Positive terminal (cathode) of the shunt reference. Nominal 3.000V is maintained between this pin and pin 2 when biased with 60µA to 15mA of reverse current through a source resistor from the supply. |
| 2 | - | passive | Negative terminal (anode) of the shunt reference. Typically tied to system ground; return path for the shunt current. |
| 3 | N.C. | unconnected | No internal connection. Leave this pin unconnected or tie it to pin 2 (negative terminal). |
