MC7805ACD2TR4G from onsemi, in a TO-263-2. 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. Must remain typically 2.0 V above the +5 V output (dropout ≈ 2.0 V). Absolute maximum input voltage is 35 Vdc. A 0.33 μF input capacitor is recommended if the regulator is far from the supply filter. |
| 2 | Ground | power_in | Common ground reference for the input and output. In the D2PAK-3 (CASE 936) package the exposed heatsink tab is internally connected to pin 2, so any heatspreader copper is at ground potential. |
| 3 | Output | power_out | Regulated +5.0 V output (4.8 V to 5.2 V for MC7805AC over temperature). Delivers >1.0 A with adequate heatsinking; internally current-limited to ≈ 0.2 A short-circuit with Vin = 35 V and thermally protected. An output capacitor is not required for stability but improves transient response; use ≥ 0.1 μF. |
