DP83TD510E: Can Vdda and Vddio use the same power supply?

Part Number: DP83TD510E


On the DP83TD510E-EVM, there is a dual LDO (U17) that has one output for Vdda and a second output for Vddio for the DP83TD510E.  In my application, Vdda and Vddio are the same voltage.  Are 2 separate LDOs required or can I just use one for both Vdda and Vddio? 

Thanks,

Cyrus
