Wake up problem for your ADP3334

Dear Sir/Madam,

 

I just designed with your ADP3334 LDO power.

 

Why ADP3334 bring the output by step up voltage like my attahced scope picture?

Our product meet the troubble by this step-up power supply.

I tried to change ADP3334 to new one, but I got the same result.

 

When ADP3334 wake up, I found much current 640mA for 338usec.

ADP3334 can drive 500mA max on your rating I know.

So this rush current "640mA per 338usec" bring the step-up output prpblem I think , correct?

 

 

Thanks, Kaos
