Hello,
For my project I want to built not so expensive (~30 eur) relatively stable 5V DC signal that would take 5V from USB power (PC or wall plug). I want to solder elements on the board myself and will source parts individually online. Power requirements are approximately 5 watt.
The way I understood the logic of the scheme. First, I should rise the voltage to some higher level (with something like TL431 but ranked for higher amp), let's say to 10V and then regulate it down with LDO to 5V?
Could some-one advise/share an electric scheme and maybe suitable components as well? If i want to do add some noise filtering what is the best way to do it?
Apologies if my question is repeating. I tried searching but have not found, so feel free to redirect me.
