If you need, say, a 5V regulator, you grab a 7805 ... The schematic notes you can also replace the IC with an MT2492. With a right-angled header, you can swap the board in for a standard 78XX.
as mentioned by several readers, you’ll want to use a 5 volt regulator ic instead of the resistor ... pin 1 is the positive (5v) terminal (which goes to the output of the 7805) and pin 4 ...
