I seem to miss a lot of details. You specify a range, but no accuracy
(short term, long term, absolute, relative, ...). Must is source or
sink, how much voltage is it allowed to drop? And most of all: "linear
solutions are not acceptable" leaves me confused. You want PWM current
switching? Or a uC with a DA and linear 'power' stage? not linear
implies steps. what is the maximum step?
