I am trying to make simple voltage regulator circuit from my 9V battery to 5V using 7805c voltage regulator. The schematic looks like this:
My question is - why the output voltage is so low? Did I fried somehow IC or I messed something with values.
One more extra question: Checking a lot of different schematics to build my circuit I found a lot of different values for each of C. So how they should be chosen? Is there any formula for that, or something?
