Abstract
A voltage regulator includes a switch coupled between an input voltage terminal and an energy storage element, a first output capacitor coupled to a first node defined between the switch and the energy storage element, the first capacitor being coupled to a first output voltage terminal, a charge pump circuit coupled to the first node and comprising a second output capacitor coupled between a second output voltage terminal and the first output voltage terminal, and a controller operable to selectively enable the switch to control voltages generated at the first and second output terminals.
