LM7808TG from HANSCHIP semiconductor, in a TO-220-3L. 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 | Vcc | power_in | Supply input pin (电源) for the LM7808; the datasheet gives the 7808 input voltage range as 11 V to 35 V, with an absolute maximum input voltage of 35 V. |
| 2 | GND | power_in | Ground pin (地), the common return for the regulator. |
| 3 | OUT | power_out | Regulated output pin (输出); the LM7808 output is 8.0 V typical (7.7 V to 8.3 V) at VI=14 V and Io=0.5 A, with a maximum output current IOM of 1.2 A. |
