I'm trying to assemble a pcb with no concrete values from the creators
( a past employee designed it and took the resistor values with him)
We have done most of it but I have been left to deal to the power
supply.
It has a 9 volt battery supplying it and we need 3V out, The pcb looks
like a 3pin regulator, with 2 resistor, one from the center leg to -ve,
the 2nd is in parrallel with output.
How do i work out the resistor values to drop the voltage?
