Thank you SUSAN XUE.
May I apologize for the tragedy that is English spelling ( Americans made a start and gave up unfortunately ), look what happens when 5 different languages are crammed into 1. Somehow Manuel only occurs in proper noun form so the spell checker thinks it is the Jewish given name.
Soon an AI spellcheck will recognize this issue.
On a more practical note. Section 4.2.1 When VRSN GND=0 your diagram sujest a resistor, is it a resistor and what is its value. Also do you know the source resistance of the 2V5?
