Hi,

Microsfot prepare desing new docking for next version surface. MP in 2Q14, 200k to 300k.

they prepare use DP130DS. power supply 3.3V,  then LDO to 1.05V, so 1.05V delay about 1ms than 3.3V. if definitely not meets the power sequence requirement. but it does work well in practice.

Due to customer power solution is fixed. customer wan to know there have any potential issue, is it ok fo rthis design?

best regards,

jeff
