How can I reduce 3A down to 1A? Answered
I am finishing up my quadcopter build, but forgot to buy an UBEC. My ESCs are OPTO, a fact I unfortunately did not realize until I had bought them. So, I am attempting to design my own circuit to reduce the 11V 3A battery I have down to 5V 1A for my receiver and flight controller board. So my question is this: can I use a simple 5V regulator to reduce the voltage and amperage? Or will 3 amps going into the circuit fry the regulator? I read that putting 2 regulators in parallel will increase current; however, I believe that is only for the output of current from the regulator(s). Any and all help is appreciated!! Thanks in advance!
