Hi, i fixing a piece of gear that had a dc-dc convertor that put out -8.5v
it was used for the VEE on a LCD display
i cant find one that does -8.5v, so i got one that does -9v
9v is too much, the contrast is off, i need between -8.2v and -8.7v
im sure i cant use a regulator since im at 9v and need only to drop 1/2v
how about a zener diode?
how would i connect it?
i got GND and -9v
i dont know the current draw the the LCD on the VEE line
its not much, my meter shows 3ma
thats not much, is that right?
anyway.. help please
mitch
