Hi!

I need a 9V /ca. 4 A Powersupply.

which parts(capacitors and voltage regulator) do i need.

Is it possible only to change the uA 7805 with a uA7809.

Is it also easy possible to get 9,6V?

Hi Moritz,

do you really need 4A? Or is this just the assumed surge current?

Maybe it’s better to take a LM138, an adjustable regulator which allows you to adjust the voltage with a pot
