US Patent 11556144 High-speed low-impedance boosting low-dropout regulator

A method for regulating a voltage reference signal includes providing a first output current during a first interval and a boosted output current during a second interval to generate a low-dropout voltage reference signal based on a first power supply voltage, a second power supply voltage, and a reference voltage level. The method includes, during the second interval, compensating for a voltage drop caused by providing the boosted output current. The first output current may be provided in a first mode of operation. The boosted output current and voltage drop compensation may be provided in a boosted mode of operation.
