Hi TI,

We want to delay vout P0V9A start-UP time,
So add RC in the ON pin.

This application is workable?Do you have any concern?

vin=p0v9

vout=p0v9a

vbias=p3v3

von=3v3 enable

thanks 

John

    Hi John, 

    Thanks for reaching out on E2E and being patient as many of us are returning from holidays. 

    If my understanding is correct, you are looking to create an RC filter on the ON pin to delay the turn-on of the device. Yes, this is possible. What kind of a delay are you looking to implement? 

    Also keep in mind that the ON pin does not have a "smart-pulldown" feature, so it is important to not leave the ON pin floating.

    Thanks,

    Arthur Huang
