Dear Stephen,

Is there any update?

Sorry for pushing you.

Thanks.

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,
