Abstract
Provided is a linear voltage regulator and method of use thereof which controls the voltage input to an integrated circuit such as a digital signal processor (DSP) or a processor. The method includes the sequential steps of generating a first ramping voltage to a load connection when the load is in a start-up phase, and generating a second operating voltage to the load connection when the load is in an operational phase. The linear voltage regulator includes a control circuit and a regulation circuit that implements the method.
