LDO output ripple controllable method based on switched capacitor array

The invention relates to the technical field of circuit structures, in particular to an LDO (Low Dropout Regulator) output ripple controllable method based on a switched capacitor array, which comprises the following steps: step 1), assembling and connecting switched capacitor integration loops; step 2), starting a switched capacitor integration loop; the low dropout regulator has the advantages that a feedback loop based on an operational amplifier in a traditional analog LDO is replaced by the switched capacitor integration loop, so that output ripples of the LDO are controllable, the LDO can be reasonably controlled among high convergence speed, stable output ripples and small area overhead of the switched capacitor, and meanwhile, the performance of the LDO is improved. According to the invention, the original tedious design process related to ripples, convergence speed and area overhead is optimized, the power consumption of the switched capacitor integration loop is reduced, and the energy efficiency is
