Abstract
Described herein are principles for designing and operating a voltage regulator that will function stably and accurately without an external capacitance for all or a wide range of load circuits and characteristics of load circuits. In accordance with some of these principles, a voltage regulator is disclosed having multiple feedback loops, each responding to transients with different speeds, that operate in parallel to adjust an output current of the regulator in response to variations in the output current/voltage due to, for example, variations in a supply voltage and/or variations in a load current. In this way, a voltage regulator can respond quickly to variations in the output current/voltage and can avoid entering an unstable state.
