I have a 3V DC power supply that is giving me 50 mV of rms noise. I would like to eliminate this noise as much as possible. Is there a calculation that makes it easier to determine what value of capacitor would get rid of most of that noise? When I put a 1000 uF capacitor on the circuit the noise goes away, but I would prefer to use either a much lower capacitor value or something else.
My usable voltage can go as low as 2.7 volts. Does anyone know of a 2.7v precision voltage reference IC that can run off of 3 volts? I can only find them at around 2.5v. (MCP1525 for example)
Thanks!
