MC7915BTG from onsemi, 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 | Ground, common to the input and output voltages as required by the standard application. |
| 2 | VI | power_in | Negative input voltage, maximum -35 Vdc for -15 V output, must stay typically 2.0 V more negative than the output even at the input ripple peak; heatsink tab is connected to this pin. |
| 3 | VO | power_out | Regulated -15 V output (-14.4 to -15.6 V at 25°C for MC7915B), up to 1.0 A with adequate heatsinking. |
