ADM7171 dropout for output voltages below 2.3V (adjustable version)

In the ADM7171 datasheet the typ/max dropouts are listed in the tables, followed by some dropout plots. There is however a note that says that these dropout specifications only apply to voltages above 2.3V. Can you provide additional dropout, PSRR, and output noise data for lower voltages? In our application we will be going from 2.5V to 1.8V at approximately 0.5A, and from 4V to 3.3V at approximately 0.5A.
