摘　　要：低压差线性稳压器随着负载电流的变化,其极点将有很大的变化,在负载电流大范围变化时,为保证稳定性需要进行频率补偿。米勒补偿是低压差稳压器中常用的一种频率补偿技术。本文对近年来提出的多种米勒补偿电路结构进行梳理介绍。With the change of load current,the pole of the low dropout regulator(LDO)will be changed.When the load current changes in a wide range,frequency compensation is needed to ensure the stability of LDO,and Miller compensation is a frequency compensation technology commonly used in low-dropout regulator.This article introduces several Miller compensation circuits used in LDO in recent years.
