A circuit regulates a voltage by controlling a voltage generator. A voltage divider is coupled between the regulated voltage and a supply voltage, and generates a sense voltage. A clamp circuit is coupled to the divider, and reduces the sensitivity between the supply voltage and the regulated voltage by substantially prohibiting the voltage across itself from exceeding a predetermined value A detector circuit is coupled between the divider and the voltage generator, and provides a control signal that deactivates the generator when the sense voltage reaches a first predetermined threshold, and activates the generator when the sense voltage reaches a second predetermined threshold. |
