Typically, devices this size can dissipate approximately 5 Watts without a heatsink.

If a 5V device were run from a 10V supply and was supplying 1A, this would be 5 Watts dissipated by the regulator.

If supplying 3A from a 10V supply, this would be 15 Watts and the device would shortly go into thermal protection.
