power supply
Noobish question. I''m trying to make a dc variable voltage power supply. I will include the schematic which I am trying to build. In the schematic there are two 1000 uf capacitors which I believe are used to smooth out the peaks of the dc voltage before hitting the regulator, but I am confused because in the schematic it shows them being grounded.
Capacitors
Decoupling capacitors connect between the power source (5V, 3.3V, etc.) and ground. It''s not uncommon to use two or more different-valued, even different types of capacitors to bypass the power supply, because some capacitor values will be better than others at filtering out certain frequencies of noise.
