    Dear Stephen,

    Is there any update?

    Sorry for pushing you.

    Thanks.

  • In reply to Dexter Choi60:

    Hi Dexter,

    It is no problem.

    Unfortunately this data is not readily available from the datasheet and the delay time is not a controlled parameter in the design.

    Typically the delay times are very short for linear regulators, it would not be uncommon to see well less than 1ms.

    Thanks,

    - Stephen

    Dear Stephen,

    It seems 1ms is long.

    could you help measure delay times of enable? 

    Thanks.

    Hi Dexter,

    I measured the delay time on the EVM board.
    The measurement was just under 300us delay.
    Please see the oscilloscope plot below.

    Thanks,

    - Stephen
