#45912 - RE: 7805 heating up....
Responding to: ???'s previous message
Mahmood,

Maybe the power supply is in current limiting with the output at ~3.3V @ 1.5A. Without forced convection, an SMT regulator with all the PCB copper it wants won't have thermal resistance much below 30 degrees Celsius per Watt.
