Abstract
A voltage regulator may include an error amplifier configured to amplify a difference between a reference voltage and a feedback voltage and generate a first amplified voltage based thereon; a power transistor between a second voltage supply node and an output node of the voltage regulator, the power transistor including a gate configured to receive a gate voltage; a buffer between a first voltage supply node and a ground, the buffer configured to generate the gate voltage based on the first amplified voltage; a voltage divider between the output node and the ground, the voltage divider configured to generate the feedback voltage based on the output voltage; and a control circuit configured to connect the output node to the ground through the gate of the power transistor based on the output voltage and the gate voltage.
