Hi,

The datasheet has a few curves on this, but the clearest one I could readily find was in the EVM user guide:

for reliability reasons with an existing design, my customer is asking for the same data for LM3490, thanks!

Hi Hanno,

This will take some time to provide, especially as the Lm3490 is on life buy status which means it is going to be made obsolete. I would highly advise against using the LM3490 for a new design. Other possible parts for this include the TLV760, TPS709, LM78LXX, etc that are not on lifebuy status.

Regards,
David

Hi David,

thanks. I know the part is obsolete. But my customer needs to solve his issue with a critically different start up behaviour of several devices in the field. That's why he's asking for our estimation about the start up time after enable.
