Abstract
A linear regulator which has a pass device coupled between an input voltage level and an output node, a voltage divider circuit for generating a feedback voltage that depends on an output voltage at the output node, and an operational amplifier for controlling the pass device, the operational amplifier receiving the feedback voltage and a reference voltage at its inputs is presented. The operational amplifier has: an input stage that receives the feedback voltage and the reference voltage at its inputs, an amplifier stage that receives an output of the input stage at its input, and a current injection circuit for sourcing current into an intermediate node between the input stage and the amplifier stage, or sinking a current from the intermediate node. The disclosure further relates to a corresponding method of operating a linear regulator.
