I found only 1uF Tanatalum Capacitors in the EE shop. Maybe a a higher capacitance of tantalum capacitor will help. 

 

Another thing, is it good to compare the input referred noise for the different types of regulators? I did a comparison between the output noise only.

I'm glad to see that the voltage regulators can give good noise performance. I wish I understood what the gain peaking features came from - maybe the choice of capacitors?
