But, even if you use a mega, you could still use this on top. With a little modification, that is. The Mega I2C pins are on a different location.

The dissipation at 150mA assuming it comes after the 5V regulator is 0.15*(5-3.3)=0.255W.
Seeing that the max dissipation at 25C is (125-25)/225[ch8776]0.444W (calculation from datasheet), you can safely pull 150mA.
