Hi
On the datasheet, the delay time for startup is 250us(typ). (from EN On to the start of soft-start.)
At this condition the VREG should be already startuped before EN-on.
However in case of EN is tied to VIN, how much will be that delay time?
At Figure 13, EN and VREG startup at same time. And that delay time looks 300us~400us.
Our customer would like to estimate the sequence time. The delay time is important for that estimation.
