About the outputvoltage accuracy of ADP2119

Hi all,

 

I have a question on ADP2119.
Regarding the ouput voltage accuracy of the fixed output version,
Do you have any data on it?
I want to achieve1.0 output voltage within 3 % errors.

So It would be great if the information of  internal FB resistors matching errors for fixed type is mentioned in the datasheet.

 

For adjustable version,
I know we can estimate it from ripple error, FB reference eroor, load/line reguration, and FB reisitors matching erros(R1/R2).

 

Thanks in advance.

 

Best ,

Tarzan
