B26 Voltage Regulator Board
This is my 26th experimental board. It will accommodate most 3-pin voltage regulators with input and output capacitors. When pins match the pattern of the 7805, the chip is mounted according to the silk screen. When pins match the pattern of the 317, the chip can be mounted backward and the board wired accordingly. I have used it both ways.
My boards each have two holes that can be used to mount the board in a project box.
