ABSTRACT:
A two-gain-stage linear error amplifier is provided with frequency compensation and independently selectable stage gains and a reasonably small compensation capacitor to promote stability with a reasonable phase margin over a wide load range so that the invention is useful as a low drop out (LDO) voltage regulator circuit device that is stable over a wide load range.
