A method for regulating a voltage in an integrated circuit device includes providing a first regulated output based upon a first voltage input range and subsequently receiving the first regulated output and providing a second regulated output based upon a second voltage input range of the first regulated output. A circuit is further provided that operates accordingly. Additionally, a clipper circuit is provided at the input to protect for over voltage conditions that may results, for example, from a charging battery to cause an output voltage of the battery to substantially exceed ordinary output voltage levels.
