I am not an electrical engineer and so I could use some help here.
We are a bit concerned about the speed controls pumping too much voltage into our APM2.
It appears our ESC's are outputting nearly 6 volts. Is this too much?
We started looking at some options. A little voltage regulator LM7805C came to mind, but it appears most suck up quite a bit of voltage (drop out voltage) ~ as much as 2 volts ~ so then the board would only get nearly 4 volts. And it sounds like that too could be a problem....yes?
So we found what is called a Low Dropout Regulator (see link). It appears this guy has a drop out voltage of only 0.15 volts at 100mA (did I read that right?) (How many amps do our APM2's need?) see specs at link below
So it sounds like if the ESC's produce anything more then 5.1 volts we could be assured of a safe 5 volts. Of course if the voltage from the ESC's gets down to 5 volts, our board would only get 4.9 volts etc.
I think I would like this little bit of insurance....am I on track or way off the wall ?
Thanks for your input.
