why my transfomer is heating too much
I have made a power supply for a ckt which requires 200ma of current and my transformer is 9Vac at 500mA.
and then i have used a bridge rectifier and a 2200uf capacitor and after capacitor i have used LM317 as i need 5.1V at 200mA.
But my transformer and small heatsink of lm317 as getting hot
so what is solution to reduce heat
my ckt remains on for 24hours daily.
Is this heating obivious and i should ignore it
