LM7915CT from Texas Instruments, in a TO-220. 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 | GROUND | power_in | Ground reference pin of the regulator, with low ground-pin current (quiescent current 1.5mA typ, 3mA max for LM7915C at TJ = 25°C). |
| 2 | INPUT | power_in | Negative unregulated input; absolute maximum −35V for the −15V part, with a 2.2μF input bypass capacitor recommended and a 30V maximum input-output differential. |
| 3 | OUTPUT | power_out | Regulated −15V output (−14.4V to −15.6V at 25°C) delivering up to 1.5A, and it requires a 1μF output capacitor for stability. |
