L7812ABV-DG from STMicroelectronics, 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 | DC input voltage; max 35 V for VO = 12 V; requires VI = 14.8 to 25 V for regulation (L7812A); bypass with ≥0.33 µF capacitor when located far from filter. |
| 2 | GND | power_in | Ground / common reference terminal; also connected internally to the mounting tab; quiescent current 4.4 mA typ, 6 mA max (TJ = 25 °C, L7812A). |
| 3 | OUTPUT | power_out | Regulated 12 V output; VO = 11.75 V min / 12.25 V max at TJ = 25 °C (L7812A, ±2 %); output current up to 1.5 A; dropout voltage 2 V typ at IO = 1 A. |
