Abstract:
Methods and systems for a low-dropout regulator may comprise a voltage regulator comprising: (a) a pass transistor having a first terminal at a control gate, a voltage input at a second terminal, and a voltage output at a third terminal, and (b) an adaptive control circuit (ACC), electrically coupled to a reference voltage and each of the terminals of the pass transistor. The ACC may determine a ΔV between the second and third terminals and cause an error signal to be applied to the first terminal to keep ΔV essentially constant as the voltage input varies. The ACC may include a voltage summing circuit electrically coupled to the reference voltage and the input voltage to generate a comparison value. An error amplifier electrically coupled to the control gate and to the voltage summing circuit may generate the error signal from the comparison value and the output voltage.
