Dear Sir/Madam,


I have a question for your LDO ADP7102.


If I do not put 100kohm RPG resister as your Fig.62 page-17 data sheet, then is the output voltage larger than designed value as formula VOUT=1.22 V{1+(R1/R2)}?


We tried to use your ADP7102 as
R1=80kohms R2=10kohms.
And there is not RPG on our PCB.
So the estimated output would be 10.98V. But we got the result around 12.7V. It was a little bit large value.
Our load is around 50mA. I think these setting are no problem.

Do you have a good advice for this case trouble?


Thanks kaos
