Hi Bob,

Q1: The minimum time from 1 to 2 is to let 3.3V rises up and be stable. There is no maximum time limitation.
Q2: The minimum time from 1 to 2 is to let VLDOIN/REFIN rise up and be stable. There is no maximum time limitation.

Please be aware that EN voltage should be equal or lower than 3.3V Vin voltage at any time.

Thanks
Qian
