EM2120L01QI About applying external voltage to VOUT pin

I want to supply power to the VOUT pin from an external regulated power supply instead of supplying power from the EM2120L01QI on the board on which the EM2120L01QI is mounted.
Is it possible to perform the above-mentioned power supply with the EM2120L01QI disabled?
I am concerned that supplying power from an external regulated power supply to the VOUT pin will destroy the EM2120L01QI.

The purpose is to flexibly change the power supply in the evaluation of the SoC that receives power from the EM2120L01QI.

Hello @shmyama1 ,

EM2120L supports the pre-bias condition, so if there is voltage applied to the Vout pin while the ctrl pin is low, there is no issue with that condition.
