HI team,

In order to calculate Rlim value, it require δCout2 and δCout3. but I'm not sure how to know it from 8.2.2.2 RLIM Resistor Selection of the datasheet.

Regards,

Hi,

It is your selected capacitor tolerance, for example a capacitor selected with 1.0uF with 10% variation. Then that delta is 10% and the capacitance due to that is 0.1uF so the 1.0uF becomes 0.9uF
