<p>A voltage regulator comprises first and second capacitors and regulation means arranged to provide a respective regulated charging current from an input terminal to each of the capacitors. The regulation means comprises at least one device through which at least a portion of the respective charging current to at least one of the capacitors is supplied. The device is controllable with a control signal to regulate current flow through the device. The regulation means further comprises control signal supply means connected to the output terminal and arranged to provide said control signal to the device, the control signal being dependent upon voltage at the output terminal such that current flow through the device is regulated according to the voltage at the output terminal.</p> |
