LDO LDO LOW RIPPLE OUTPUT VOLTAGE DIGITAL LDO DEVICE USING A COMPARATOR WITH COMPLETION SIGNAL AND METHOD OF OPERATING DIGITAL LDO DEVICE

摘要

The present invention utilizes the comparison completion signal as a clock of the shift register, so that the comparison result by the comparator is reflected in real time so that the shift register can quickly determine the number of pMOS transistors that are turned on and activated to maximize the output voltage ripple. Disclosed are a digital LDO device and a method of operating the digital LDO device, which reduce output voltage refill by using a comparator comprising a completion signal, which reduces.
