When I use feedback resistance of 100 ohm and feedback capacitance of 2 pF. I am facing ringing effect. So, how do we select the capacitance according to the resistor.

It isn't ringing; it's oscillating, because you're not using the LTC6269-10 correctly.When I use feedback resistance of 100 ohm and feedback capacitance of 2 pF. I am facing ringing effect.
As always, read the data sheet. Pay particular attention to pages 13 and 14 to determine the correct component values. Be prepared: there's maths involved.So, how do we select the capacitance according to the resistor.
