LM4040AIM3-5.0 from Texas Instruments, 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 | Cathode | passive | Cathode (+) terminal. Shunt current input / regulated output voltage node, nominally 5.0 V above the anode. Drive through a series resistor R_S from V_DD to sink 60 µA-15 mA. |
| 2 | Anode | passive | Anode (-) terminal, normally grounded in a shunt-reference configuration. |
| 3 | NC | unconnected | No connect. Must be left floating or tied to pin 2 (anode). |
