Load fluctuation data for ADP2120

Kaos on Jan 15, 2014

Dear Sir/Madam,

Do you have the data of the load fluctuation for ADP2120?

eg; 0.2A ---> 1A curent grow up as transient.

I cant find it on your datasheet.

Only found 0A at max output on Fig.24,27, it is the load transient.

Thanks Kaos

Kaos,

load transient depends on the ammount of capacitance added to the output.

You may want to consider using the ADP2120 design tool to identify how much capacitance you will need for a specific transient requirement.
