Abstract
A voltage regulator circuit comprises a regulator output; an amplifier that is activated in response to a first signal and inactivated in response to a second signal, the error amplifier having a first input for receiving a reference voltage, a second input for receiving a feedback voltage, and an output that generates a differential with respect to the reference voltage and the feedback voltage; an active discharging transistor that, in response to a falling slope of the electronic signal, discharges a present electronic signal at the regulator output; and a first switch at the output of the amplifier that is in open state in response to a receipt of the second signal to disconnect a coupling capacitor path between the regulator output and the reference voltage to negate an effect of noise on the reference voltage in response to the falling slope of the electronic signal.
