If you are talking about filtering out spikes and transients, that is only a side issue and not a control of voltage like one would see in a voltage regulator. If you are using a red diode you should know the the forward voltage is going to be low and therefore you wouldn't use a boost driver on that diode. If you are using a 490nm diode, you should know the forward voltage is quite high and you would want a boost driver. But, in the end, they are all just current regulators and nothing more. You can add a TTL input for PWM control of the output or and analog control that will vary the current between two set points, but it is still just a current regulator.
