摘要
A low dropout voltage (LDO) regulator including: a coarse loop circuit configured to receive an input voltage, generate a coarse code and adjust a coarse current according to the coarse code; a digital controller configured to receive the coarse code and generate a fine loop control signal according to the coarse code; and a fine loop circuit configured to receive the input voltage and the fine loop control signal and adjust a fine current according to the input voltage and the fine loop control signal, wherein the coarse current and the fine current adjust a level of an output voltage.
