Is it possible to design a voltage regulator meet such spec?

[Analog_starter]

On chip design, 1.8V~2.5V input to 1.6V output
capacitance loading: 0~20pf
Peak current loading: 20mA (freq. 20Mhz)
undershoot deltV <100mV
Is it possible to get so small transient undershoot responds with less 10pf capacitance compensation on output node?
Thanks!

Hi
I am seeking the kind of same design, I can kind of reach it but with an very low efficiency? Did you get your design?
Thanks

Not yet. I still need help.
Could you share your idea with me?
I need very small area, so can't put a big capacitance on the output node...
But I also want to undershoot as small as possible when there is a big peak Iloading.
Thanks.
