Questions
How big is the LM78xx regulator PCB?
It measures 41 × 42 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LM78xx regulator use?
7 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LM78xx regulator KiCad files?
From the ptdog6/kicad repository on GitHub, at the commit this page was made from: the board is LM78xx_regulator.kicad_pcb and its schematic LM78xx_regulator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LM78xx regulator design in my own project?
Its repository states no licence, so its author keeps all rights: ask ptdog6 before reusing the design.
