Abstract
In an exemplary embodiment, a system ( ) is formed to include a semiconductor device ( ) that is formed to function as a voltage regulator. The semiconductor device ( ) is formed to have a control loop that includes an amplifier ( ) and a feedback transistor ( ) that provide a small signal AC gain that varies inversely to a load current of an output transistor ( ) in order compensate for the manner in which the output transistor ( ) transconductance depends on the load current flowing through the output transistor ( ).
