A voltage regulator has an input terminal, an output terminal, a first transistor to intermittently form an electrical circuit between the input terminal and the output terminal, a rectifier connecting an intermediate terminal in the electrical circuit between the input terminal and the output terminal to ground, a controller that drives the first transistor, and a capacitorless filter. Capacitance for the filter function can be provided by a capacitor, e.g., the input capacitor of the load, located in the load chip or on the same printed circuit board as the load chip. The capacitorless filter can include an inductor connected between the intermediate terminal and the output terminal, or the inductance can be provided by parasitic effects in the connections between the voltage regulator and load.
