Abstract
In a linear voltage regulator, a first stage outputs an output signal. The first stage is configured with a first switchable bias current, and is configured to receive a feedback signal. A second stage provides a regulated voltage output. A decoupling capacitor is coupled to the regulated voltage output. A feedback circuit is coupled with the second stage and configured to generate the feedback signal. A frequency compensation circuit includes a second switchable bias current. The frequency compensation circuit: pushes away an existing pole to a higher frequency when the first and second switchable bias currents are operated in a sleep mode; and creates a left-hand-side zero when the first and second switchable bias currents are operated in an active mode. The active mode comprises the first and second switchable bias currents supplying greater currents than are provided in the sleep mode.
