In sometimes when friends want to modify negative voltage source from the outside is positive voltage. We try to come to see this circuit use op-amp IC LM741, be usable easily and, It can change R1,R2 for fix the expansion ratio has of the circuit with. See the detail in the circuit adds.

If you want positive voltage regulator 9Volt. I sizes beg for to suggest the nine s wander this , because it easy is good, the equipment is , seek easy with see the circuit has already. Friends must appear familiar certainly. It uses transistor ordinary just this , by friends use get many the number [...]
