LM7805L-TA3-T from UTC Unisonic Tech, 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 | Input | power_in | Unregulated input supply; the absolute maximum input voltage is 35 V for the 5 V to 18 V output versions (VOUT=5~18V). |
| 2 | GND | power_in | Common ground return; the notes for use require the GND pin to be at the minimum potential in all operating conditions. |
| 3 | Output | power_out | Regulated 5 V output rated for up to 1 A (IOUT max 1 A); the notes for use recommend a maximum output capacitance of 1000 µF. |
