LDO LDO METHOD AND DEVICE FOR CONTROLLING DIGITAL LDO REGULATOR

摘要

Disclosed are a method and device for controlling a digital LDO regulator. The method for controlling a digital LDO regulator according to an embodiment of the present invention includes a step of generating a trigger signal in conjunction with the input of a clock, a step of outputting a result of a specific comparator operating in accordance with the generation of the trigger signal, among a plurality of comparators, to a shift register, and a step of adjusting a current supplied from a plurality of P-type metal oxide semiconductors (pMOS) by using a combination of the resultant value and the previous resultant value previously output to the shift register. It is possible to adjust the size of an output voltage at a quick response speed.
