英文摘要：

An improved linear voltage regulator used in MCU is presented. The new regulator modifies the reference voltage to the output voltage level to avoid using the resistor divider network. The stability and response speed of the whole loop are greatly improved. This circuit is fabricated in 90 nm CMOS technology. The measured results show the new regulator achieved a stable output voltage with a low ripple （10 mV）, high accuracy （2%）. The quiescent current is less than 100μA.
