Hi - I need a DC/DC converter/controller that gives about a +-12V regulated output. It can be less than that or greater than that, but it needs to be very clean. Load current should peak at under 1ma on both lines. I have 3.3V and 5V supplies available. I feel like this should be a very basic, simple, common component but I can't find any parts that meet these specs. I'm thinking I'm just searching for the wrong thing. I found the MAX680 which mostly looks OK, but it's not regulated.
Any suggestions? I can't believe I'm having difficulty finding such a part.
