Hi All, I've been messing around in the KiCad schematic editor. I've come up with this schematic for a power supply.
I've got a 40VA transformer going to a bridge, the output of which is about 37V. Then I've got a capacitor, a voltage divider (to get the voltage into the range of the 78XX which is 35V max), then capacitors on the outputs.
I've breadboarded this and it works, but the resistors I used are the wrong rating, it works but they get hot. Is this all I need for a simple regulated supply?
Anyone have a recommendation on capacitor sizes?
I attached the schematic as a pdf.
thanks
