LM7915T from HGSEMI, 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 | GND | power_in | Common ground reference pin of the LM79xx negative regulator; the datasheet gives no electrical limits for this pin. |
| 2 | Input | power_in | Negative unregulated input supply; the absolute maximum input voltage is -35V at TJ=25°C. |
| 3 | Output | power_out | Regulated negative output of -15V nominal for the LM7915, specified from -14.44V to -15.56V at 5.0mA to 1.0A load, with output current in excess of 1.0A. |
