L7812ACV

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220

L7812ACV 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 Unregulated DC input voltage, rated up to 35 V absolute maximum for the 12 V output version, with VI = 14.8 to 25 V for the specified 12 V output range.
2 GROUND power_in Common ground reference for input and output, also connected to the metal tab of the TO-220 package.
3 OUTPUT power_out Regulated 12 V output (11.75 to 12.25 V at 25 °C) delivering up to 1.5 A with internal current limiting and thermal shutdown.
