Many DIY projects require a small Power Supply.
The 78XX family is ideally suited for this job, and with this little PCB you can easily build small Power Supplies for virtually every application.
The circuit is very simple:
The Alternating current is applied to X1 and rectifies by B1.
It charges a large Capacitor C1 to power the regulator.
The output voltage depends on the Regulator you use, e.g. 7805, 7812,7815…
Dimensionierung:
C1:4700u, with sufficient voltage Rating!
C2:0.33u
C3:0.1u
The Heatsink should be enough for devices with moderate power consumption.
