9v DC to 3v DC and 1 9v DC to 2 9v's and 1 3v need some help ???
david656:
im doing a little project and need to step down 9v DC from the wall to 3v DC... what would i use to create this effect ?
and how do i wire 2 seperate 9DC things to the same DC plug/transformer? do you do it in series or parallel or ?
any insight would be great !
thanks
Ed_McCarron:
2 separate devices to one power supply? Parallel. Just be sure that the current rating on the PS will handle both devices.
9 to 3v? http://www.dimensionengineering.com/DE-SW033.htm is a hybrid switching reg - in a 78XX footprint. It'll handle up to 1A at 3.3v.

I take it you are using a 9v DC 'plug' PSU? Why not just get a 3v one? [Here's one] from Maplins for £6.
david656:
if i got another lead/ transformer it would just be taking up more room in a confined area :-( and therefore not reallly a option ! if worst comes to the worst im gunna have to use batteries which will run down in no time :-(
can i not use a load of resistors or summit !?
