We are not crossing the maximum limit of the load on the rail per datasheet. We just changed the output capacitor in the platforms and saw deviation. I think I need to go again to Vendor to find out that why changing of capacitor making the deviation in ramp delay and what is the relation. Probably, that may help here.
