Yes but I would expect that it takes 60mA no matter how you power it.
With the additional wattage being dissipated as heat in the regulator?
ambient temp 50c (remember a hot IC heats the air around it, and I don't have a fan on mine!)max IC temp 125 c (150 is abs rated max, 175 is thermal shutdown)pad size 11x11mm (this is conservative, as i don't konw the copper weight, i am ignoring the bottom pad because vias do not conduct heat too well, the actuall top pad is about 10.8x8.1mm, bottom is 10.8x17.5)this gives a 95CW thermal resistance(125C-50C)/95(CW)=.79 Wor 66mA @ 12 v113 mA @ 7 v
