Abstract
An ultra low drop out power regulator is described. The power regulator may be used, for example, where a dynamically fast, and electrically clean power supply at the point of use is required. The power regulator is provided as a single part with two input voltages. The higher voltage input drive the output stage so that ultra low drop out is achieved. The disclosed regulator is therefore more efficient, resulting in less heat dissipation. The regulator is packaged in a stand up package thereby reducing board space. By use of a stand up package, air flow to other components is not blocked.
