Abstract
A regulator circuit having a voltage output terminal is provided. The regulator circuit includes a current mirror module, a plurality of source followers, and a switch. The current module receives a driving voltage, and has a first current terminal coupled to a driving current and a plurality of second current terminals, so that the driving current is copied to each second current terminal. Furthermore, each of second current terminals is coupled to one of source followers respectively. An output terminal of each source follower is coupled to an input terminal of next source, and the input terminal of the first source follower receives a control voltage. So that the source followers can determine whether the switch conducts the driving voltage to the voltage output terminal or not according to the copied driving current and the control voltage.
