LM4040C50ILPR from Texas Instruments, in a TO-92-3. 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 | * | passive | Substrate pin; must be left floating or connected to anode in high-EMI applications. |
| 2 | CATHODE | output | Shunt reference cathode output providing 5.0V regulated reference voltage stable from -40°C to 85°C with 100 ppm/°C temperature coefficient. |
| 3 | ANODE | power_in | Anode/ground reference; provides return path for reference bias current, typically connected to system ground. |
