AD9548 Dev Board Power Supplies

I'm looking at using the AD9548 in a design and I've been investigating power supply requirements. I've noticed that the ADP150 linear regulator is used to supply the 1.8V DVDD Supply. The ADP150 is specified to deliver 150 mA max current, yet the AD9548 Data sheet specifies a typical DVDD current of 190 mA.  I'd like to follow the eval board design as much as possible but I can't see how the ADP150 can supply sufficient current. Am I missing something?
