Supply Voltage ADF4159 3.0V vs 3.3V

it seems that the LDO for the ADF4159 was changed from 3.3V to 3.0V in both eval boards EV-RADAR-MMIC2 and EV-ADF5901SD2Z. The LDO U4 is listed in the schematics as 3.3V, in the BOM it is stated as the 3.0V equivalent. As both the description and the partnumber state it as 3.0V regulator I assume this change is correct. Therefore I was wondering for what reason this change was done. Any performance differences or issues with 3.3V?
