L7815ABV-DG from STMicroelectronics, in a TO-220. 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 | INPUT | power_in | Unregulated positive DC input (VI). For a 15 V output the recommended input range is typically ~17.5 to 30 V (dropout ~2 V at 1 A, absolute max VI = 35 V for VO = 5-18 V). Bypass to GND with a small ceramic capacitor (~0.33 uF) placed close to the pin to suppress oscillation, especially when the raw supply is more than a few cm from the regulator. |
| 2 | GND | power_in | Common ground for both the input and output rails and reference for the internal error amplifier. Electrically bonded to the DPAK exposed back tab, which is the primary heat-conduction path to the PCB copper pour. |
| 3 | OUTPUT | power_out | Regulated +15 V DC output (VO). Guaranteed 14.4-15.6 V over line, load and temperature (2% A-grade spec) with up to 1.5 A load current when the package is adequately heatsinked. A ~0.1 uF ceramic to GND close to the pin is recommended for transient response; larger bulk capacitance improves load-step behavior. |
