L298N gets very hot

Hi,
Does anyone one why my L298N would get very hot? Is it a result of too much voltage or too much current? I have a 12V 200mA transformer
that I use as the power supply for my circuit... is this crazy? I tried a 9V battery and no current would flow through the circuit, so what is an ideal power source?
Thanks! julia

Your question lacks context.
Is this a commercial product or homemade? Did it work before?
If homemade, What is the circuit? Where did you get it?
More details are required. Lots more.

Heat production is related to the voltage drop *across* your device [power-in terminal to power-out terminal] times the current flowing through it, V*I measured in watts, so it might be too much of either or both V or I.
