Abstract:
A low noise voltage regulator generally includes an output switching stage and an amplifier, both of which contribute current to produce an output voltage at a substantially constant level. The amplifier produces a current that is based on a difference between a reference voltage and a feedback of the output voltage. The current from the amplifier (and optionally also from a current ramp generator) counterbalances the current from the output switching stage to maintain the output voltage at the substantially constant level. The output switching stage is controlled in response to a level of the counterbalancing current.
