Hi Toshiro,

There is a diode OR from PMID (powered from VBUS) and SYS. When powered by only by battery, the regulator output to REGN pin is disabled.

Jeff

Thank you very much. I understood. one more question is the output voltage in all of VBUS operating voltage rage of 3.3V to 14.5V. Does it keep 5.5V to 6.5V in 6V or higher and dropout in 3.3V to 6V?
