Abstract
A linear regulator device and a configuration method thereof are provided. The linear regulator device includes a digital-to-analog converter (DAC), an operational amplifier (OPAMP), a switch, and a resistor. The DAC provides a controlled current according to a control signal. An inverting input node of the OPAMP is coupled to the DAC. An output node of the OPAMP is an output node of the linear regulator device. Input nodes of the switch are received multiple reference voltages respectively. The control signal is received by a control node of the switch. The output node of the switch is coupled to a non-inverting input node of the OPAMP. The resistor is coupled between the output node and the inverting input terminal of the OPAMP. A current inversion point of the linear regulator device is determined by one of the multiple reference voltages corresponding to the control signal and the controlled current.
