Would like to use an LT3045 and LT3094 as tracking linear post-regulators to generate +/-3-6V supplies (that track eachother) - with a high-speed opamp (e.g. AD8610 or AD4625-1) in the feedback loop. Are there any special precautions in doing so?
I've got the AD8610 in the circuit now, and it does well, as far as I've been able to evaluate it. Except that on the -5V input, there is a very noticeable 2-3% error. I think my input is too close to the rails.
