in the datasheet example, R1=360K, and the calculate Cff=17.6pF with the following formula, but finally we choose 22pf not 18pf. Could you please give me an explanation?
Thanks & Best Regards,

22pf is a standard capacitance value close to 17.6pf, and our design has a big margin for the loop, though 22pf also a value that can meets the design requirements.
