I have a circuit which needs to operate on 5 VDC and measured current is 208.5 mA. The power supply generates +12V (max 2 amps). I wired the regulator as you normally would (per datasheet), .33uF cap on input voltage line to ground and a .1uF cap on output voltage to ground. However, with a heat mount on the regulator, and a high watt resistor (to bring the input voltage down some) the regulator still is over heating. I have never ran across this issue before using a 7805 (1amp max out). Any ideas, suggestions?
Thanks
