Abstract

The present invention discloses an overshoot protection circuit (1) and its method thereof. The circuit (1) comprises a current load sensor (13), an AC coupled circuit (14), a pull-down transistor (12), a non-inverting amplifier (11), where the non inverting amplifier (11) is operable between an inactive mode and an active mode to maintain the non-inverting amplifier (11) in an idle state and initiate the non-inverting amplifier (11) for signal amplification respectively based on a detection of the current load level of the main low-dropout voltage regulator (2) by a current load sensor (13). The circuit (l) is operable by detecting current load level of the main low-dropout voltage regulator and thereby instructing a non-inverting amplifier (11) to switch between an inactive mode and an active mode based on the detected current load level, transmit a signal to the non-inverting amplifier (11) for signal amplification upon a detection of spike on the regulated output voltage, and suppress the overshoot voltage to a stable voltage upon receiving the amplified signal from the non-inverting amplifier (11).
