Voltage regulator with fast overshoot settling response

A method, comprising:

• regulating a voltage at an output node of a voltage regulator using an error amplifier;
• determining when the voltage of the output node is coupled up above a regulated voltage to a first voltage;
• enabling a discharge path connected to the output node when the voltage of the output node is coupled up above the regulated voltage to the first voltage;
• determining when the voltage of the output node falls below a second voltage which is greater than the regulated voltage and the first voltage;
• and
• disabling the discharge path when the voltage of the output node falls below the second voltage.

An apparatus, comprising:

• an error amplifier, the error amplifier comprising a first output, a second output, an inverting input and a non-inverting input;
• a power stage connected to the error amplifier and to an output node;
• and
• a discharge path connected to the output node, wherein the first output is configured to control the power stage and the second output is configured to control the discharge path, and the error amplifier comprises means for detecting a level of a current in the error amplifier and means for setting a signal on the second output in response to the means for detecting the level of the current, wherein the signal has a first value when the current increases above a first threshold and the signal has a second value when the current subsequently falls below a second threshold.
