Re: How hot is too hot? #ubitx


 

What you can always do to reduce the load and heat on the poor ol' 5V Regulator is to just add a series resistor of adequate wattage to drop the regulator input voltage to 7V or so. Simple, but not as efficient as using a buck regulator for the 5V in the first place....important if you are off battery power.? ??
