This article designed a three-terminal voltage regulator circuit with adjustable output. The circuit can be applied in fields such as sensors and power management that require higher precision voltage standards. In this paper, 2.5 V and 5 V are selected as the output reference voltage, and they are subjected to 0~40 V power scan and0~70℃ temperature scan. The output reference voltage change is lower than 0.28 V.
