Hello,

I have a question about LM2733.

I wonder how long will take time from input to output.

I can't find the information on spec. document.

Hi JH,

I just took a quick measurement on EVM, the time from Vin above 1.5V to Vout reaches the regulated target is around 3ms.

thank you for your reply.

I have another question.

Is there another way to control that time? For example, by adding capacitance.

Hi JH,

There is no soft-start control pin for LM2735.

So if you need a longer start time, you may refer to this APP NOTE.

Lei
