... APPLICATIONS NOTES Remote Sense Remote sense operation can be easily obtained with the CS5253B−8 but some care must be paid to the layout and positioning of the filter capacitors around the part. The ground side of the input capacitors on the +5.0 V and +3.3 V lines and the local V IC must be tied close to the ground pin of the regulator ...
