Zusammenfassung:A voltage regulator comprises an output transistor (MPOUT) with a controlled section connected between a first supply terminal (VS) and an output terminal (OUT). An amplifier (AMP) comprises a reference input (VR) and a feedback input (VFB). A current mirror comprising a replica transistor (MREP). The current mirror is configured to mirror and attenuate a load current supplied by the output transistor (MPOUT) to the replica transistor (MREP). A filter circuit (RC) is coupled to a controlled section of the replica transistor (MREP) and coupled to the feedback input (VFB) of the amplifier (AMP) via the output terminal (OUT). 一种电压调节器,包括具有连接在第一电源端子(VS)与输出端子(OUT)之间的受控部分的输出晶体管(MPOUT)。放大器(AMP)包括参考输入(VR)和反馈输入(VFB)。包括副本晶体管(MREP)的电流镜。电流镜被配置为镜像并衰减由输出晶体管(MPOUT)供给副本晶体管(MREP)的负载电流。滤波器电路(RC)耦合到副本晶体管(MREP)的受控部分,并经由输出端子(OUT)耦合到放大器(AMP)的反馈输入(VFB)。
