onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220
MC7906CTG 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 pin; a common ground is required between the input and output voltages, and the regulator has no external sense lead, so ground-loop and lead-resistance drops should be minimized. |
| 2 | VI | power_in | Unregulated negative input; the input voltage must remain typically 2.0 V above the more negative level even during the high point of the input ripple, and the heatsink surface is connected to this pin. |
| 3 | VO | power_out | Regulated negative output (−6.0 V nominal for the MC7906C), capable of output currents in excess of 1.0 A when adequately heatsinked. |
