i m doin 1 project where i need 2 supply power 2 ADC AD677 ... i need
+/- 5/12 volts..i want this all frm single chip instead of using
7805,7812,7905 & 7912.
can u help me
In order to get a more helpful answer, you have to tell what you've got
as an input voltage, and how much power you need for the other stuff.
I'm also wondering where your requirement for -5VDC is coming from --
the AD677 only requires a +5 for logic and a +/-12V for the analog
side.
Apart from all that, no single IC exists that can do what you want.
Linear regulators are cheap and efficient -- splurge a little. But if
you want maximum simplicity or absolute minimum space, try purchasing a
small AC-to-DC converter which will give you the three voltages.
And please hold off on the text lingo unless you're kidnapped and are
being confined in a car trunk. It gives the impression you can't even
be bothered to express yourself clearly. That's not a good impression
to give if you're asking for someone to craft a ldetailed, cogent
answer.
Good luck
Chris
