How do i make -8V from 12V power?
How do i make -8V from 12V power?
Do i just need to use
-8V regulator(7908) and connect like this?
then will I get -8 from X?Code:|---------------| | 7908 | ----------------- | | | | | | 12V Ground X
is that all i have to do it? or do i need other stuff too?
let me know about this and if you have good web site about this or schematic..
PS: i am trying to Sharp 6" work so i need 12V(from car) 5V(http://www.hut.fi/Misc/Electronics/circuits/vga2tv/psu_5v.html) and -8V...
LQ6RA01 from eio.com(and bought from jay) i think.. and have only bare LCD part

"If one more body-kitted, cut-spring-lowered, farty-exhausted Civic revs on me at an intersection, I swear I'm going to get out of my car and cram their ridiculous double-decker aluminium wing firmly up their rump."
I was jus designing almost free DC-DC ps for myself and I found this:
MAX765
This will make -12V@ ~500mA from 5V
It will easily do -8V if you use 7908 after that circuit and 7805 before.
You need only few parts besides that and they all are easy to get!
