... Fixed Parts driven from another (Master) regulator the two outputs will track each other until the Master exceeds the target voltage of the Slave regulator. Typically the output of the MIC68400 will track above the RC input by 30mV to 70mV. This offset is designed to allow Master/Slave tracking of same-voltage regulators ...

... Also, when RC is driven in tracking mode, pulling EN low will not cause the output to drop. Maintaining low EN in tracking mode simply means that the MIC68400 will shutdown when the tracking voltage gets near zero case can the MIC68400 enter the tracking mode unless EN is pulled high.
