LM4040D30IDBZR 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 | Shunt current/voltage input (cathode of the reference). Regulates to 3.0 V above the anode when biased through a series resistor RS. Recommended cathode current 45 µA to 15 mA. |
| 2 | ANODE | passive | Common pin, normally connected to ground. Return path for the shunt current. |
| 3 | SUB | passive | Substrate connection. Pin 3 is attached to substrate and must be connected to ANODE or left open. |
