<p>A circuit regulates a voltage by controlling a voltage generator. A voltage divider (24) is coupled between the regulated voltage (Vint) and a supply voltage (Vcc), and generates a sense voltage. A clamp circuit (22) is coupled to the divider (24), and reduces the sensitivity between the supply voltage (Vcc), and the regulated voltage (Vint) by substantially prohibiting the voltage across itself from exceeding a predetermined value. A detector circuit (26) is coupled between the divider (24) 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.</p> |
