Hi,

yes I used the right sheets for 9V and for 5V (latest files newly downloade)

R4 10k
R5 12k
= 8.947 V

= 9.006 V

Try this.

Hi,

after adding R5 12K and R6 820K i get exactly 9,06 V  :-D :-D :-D
Thnk you.
For my 5V board I get 4,91 V out. How would I ge closer to 5V?

It has no importance of having exactly 5 volts but it may feel better. Can you tell me what you have as R4, R5 and R6? Measure also the voltage across R5. I'll calculate this for you.
