ADP2389 Output Voltage

I would like to use ADP2389.

So, I have a question.


#1  When I used ADP2389, when the load was changed from 0 to 9 A, the output voltage fluctuated by about 10 mV.

      Is this characteristic of the IC?


      The conditions of the regulator are as follows.
      Switching frequency: 1200 kHz
      Input voltage: 5 V
      Output voltage: 1 V


#2  Is there a way to improve load regulation?


Best Regards,
