ABSTRACT:
A linear voltage regulator circuit includes an external pass transistor that does not rely on internal compensation, provides high gain, and exhibits reduce silicon area and power requirements. Circuits according to the present invention provide sufficient bandwidth with an error amplifier and drive capability to keep any secondary poles sufficiently far from the unity gain bandwidth (UGB) while maintaining good power supply rejection.
