Abstract
A low drop out voltage regulator () that receives an input voltage and generates a substantially constant output voltage includes a gain stage (), a buffer stage (), an output driver transistor (), and first and second load current sense circuits (). The first load current sense circuit is connected between the output driver transistor and the buffer stage and adaptively increases a bias current of the buffer stage as a function of the load current. The second load current sense circuit is connected between the output driver transistor and the gain stage and adaptively decreases a bias current of the gain stage as the load current increases.
