  • Method and apparatus for optimizing linear regulator transient performance
    Patent number: 9041369
    Abstract: A voltage regulator compensation circuit provides power to a dynamic load and includes a power transistor configured to drive the dynamic load, a reference determining transistor configured to establish a voltage reference proportional to a regulated output voltage of the power transistor, and a control circuit coupled to a gate input of both the power transistor and the reference determining transistor. Also included is a comparison engine configured to compare the regulated output voltage and the voltage reference, and a current consuming transistor operatively coupled to an output of the power transistor and configured to provide a varying secondary load. The comparison engine is configured to control the current consuming transistor to increase current draw or decrease current draw from the power transistor based on the difference between the regulated output voltage and the voltage reference.
