7815 from YFW, in a TO-252. 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 | Input | power_in | Unregulated input supply; the 7815 electrical characteristics are specified at VI = 23V and tested over VI = 17.5V to 30V, with short-circuit current measured at VI = 30V. |
| 2 | GND | power_in | Common ground pin of the regulator, listed as pin 2 in the TO-252 pinout. |
| 3 | Output | power_out | Regulated 15V output, specified at 14.40V to 15.60V for Tj = 25°C and IO = 5mA to 1A, and at 14.25V to 15.75V over the full input and load range; peak output current is 1.8A. |
