Abstract
The present invention provides a low drop-out voltage regulator (200) that reduces gate capacitance and simplifies the compensation needed to maintain stability, without requiring additional and/or larger Miller capacitors (108), by splitting the output (220, 221) of the driver (112A) for different operational modes, selectively driving a small power device (206), a large power device (214) or both based on the mode.
