One of my customers has one problem with ADR03 output adjustment range.
Part of his circuit schematics is attached.
As shown in the schematic, Vout adjustment circuit is almost the same as shown in the data sheet, Figure 35.
He said that the Vout adjustment range is 2.485 to 2.5005 in his circuit, although data sheet said that adjustment range is 2.3V to 2.8V.
Could you advise us what is the problem in his circuit?
He sent me another question.
The data sheet said that the “ADR01/ADR02/ADR03/ADR06 trim terminal can be used to adjust the output voltage over a nominal voltage”, in page 15. In this sentence, what is the nominal voltage value?
Thank you for your help,
