Abstract
Multi-stage amplifiers, such as linear regulators, configured to provide a constant output voltage subject to load transients, are described. The multi-stage amplifier includes a first amplification stage which activates or deactivates a first output stage in response to an input voltage at an input node. The first output stage is configured to source a current at an output node of the multi-stage amplifier from a high potential, when activated. Furthermore, the multi-stage amplifier includes a second amplification stage configured to activate or to deactivate a second output stage in response to the input voltage at the input node. The second output stage is configured to sink a current at the output node of the multi-stage amplifier to a low potential, when activated. The first amplification stage and the second amplification stage are configured to activate the first output stage and the Second output stage in a mutually exclusive manner.
