First of all let me thank everybody for his/her input.
My intention though was not to start a complicated thread, so please people do not fight over this question. I think each of you provided interesting and valuable feedback! :-)
The application is to provide termination voltage (3V) to a bus...
Does anybody know of a single IC voltage regulator (5V input) that would be capable of both sourcing and sinking up to 1.5A or 2A (when the output is at 3V)?
Thank you
