LM4040D50ILP 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 | Must be left floating or connected to the anode; TI recommends connecting it to the anode in applications with high EMI or significant high-frequency switching noise. |
| 2 | CATHODE | passive | Parallel current/voltage input; cathode current must be supplied, with a recommended maximum of 15 mA and an absolute maximum continuous cathode current of 25 mA (-10 mA minimum). |
| 3 | ANODE | passive | General-purpose pin, normally connected to ground. |
