Abstract
A hard saturation mode of operation can be avoided in an LDO regulator by providing an additional feedback control loop. The additional control loop cooperates with the LDO regulator's amplifier stage and output stage to maintain at least a minimum desired voltage drop across the output stage from the power supply to the load.
