L7818CV from MSKSEMI, 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 | IN | power_in | Unregulated input pin; the datasheet gives an absolute maximum input voltage of 35 V and specifies regulation for Vi from 21 V to 33 V. |
| 2 | GND | power_in | Ground pin of the three-terminal regulator, listed as pin 2 in the pin assignment. |
| 3 | OUT | power_out | Regulated 18 V output (Vo 17.1 V to 18.9 V for Vi 21 V to 33 V and Io 5 mA to 1 A) with a maximum output current IOM of 1.5 A. |
