Which resistor is responsible for the drop of volts ?. it is the R25 (47R) . Can I choose a lower value for this?
Yes. You could jumper it and remove D4 if you are going to be using a regulated power supply. Sometimes the charge pump can try to draw too much current and that little bit of resistance becomes a problem. (Did you use the LT1054 for the charge pump?)
Seconded. Jumper the resistor and see what the measurement is after that.
