A configurable voltage regulator ( 128 ) operable in either of two selectable modes or topologies is disclosed. In one disclosed embodiment, the voltage regulator ( 128 ) can operate as a charge pump regulator or a switching regulator, to generate a negative polarity regulated voltage. The voltage regulator ( 128 ) includes an output driver ( 80 ), for example including first and second drive transistors ( 81 A, 81 B), that are used in both of the selectable modes.
