Abstract
Disclosed are methods, circuits, apparatuses and systems for providing power to a dynamic load such as a non-volatile memory array. According to embodiments, a voltage source may be adapted to generate and output a supply current at substantially a target voltage through a regulating transistor whose channel is in series between an output terminal of said charge pump and an input terminal of said NVM array. A discharge circuit branch coupled to an output terminal of the regulating transistor may be adapted to drain away current from the regulating transistor output terminal when a voltage at the regulating transistor output terminal exceeds a first defined threshold voltage. A bulk regulating circuit branch coupled to a bulk of the regulating transistor may be adapted to reduce a bulk-voltage of the regulating transistor when a voltage at the regulating transistor output terminal exceeds a defined threshold voltage.
