Abstract
An amplifier circuit includes an amplifier and an output transistor. The amplifier is coupled to an output node of the output transistor for providing an output voltage to a load device. The amplifier circuit also includes a slew-rate control circuit coupled to a gate node of the output transistor and configured to control voltage rise of the gate node of the output transistor during power-up to reduce output voltage overshoot.
