Abstract:
1. A voltage regulator comprising: a voltage generation unit configured to compare a reference voltage level with a voltage level of a first node and generate an output voltage; a first resistor section comprising a first sub-resistor and a second sub-resistor between the first node and a ground voltage node, wherein the first resistor section is configured to control a connection between the first sub-resistor and the second sub-resistor to change a resistance value of the first resistor section; and a second resistor section comprising a reference resistor, a plurality of unit resistors, and a plurality of step resistors, wherein the second resistor section is configured to control connections of the unit resistors and the step resistors to change a resistance value of the second resistor section, wherein the first resistor section and the second resistor section are serially coupled between an output terminal of the output voltage and the ground voltage.
