It was tested for 15 minutes.
The electric current was between 1.0A and 2.0A on the test.
The regurator with heatsink was hot.But that does not exceed 60 degrees(c).
I can touch the regulator.On the datasheets

both chips can operate .
If you worry the heatdamage,drill some cooling hole on the case body.
