Patent ID: 8872489

Claim:
A regulator, comprising: a current path unit coupled between an input terminal and a ground terminal and configured to include a first current determination unit coupled between the input terminal and a control node and configured to supply a high voltage of a high voltage generator to the control node so that a first or second current path each having a different current load is selected depending on a voltage of the control node, and a second current determination unit coupled between the control node and the ground terminal and configured to control the voltage of the control node by changing the current load depending on an input voltage; a voltage supply unit configured to supply the high voltage to an output terminal depending on the voltage of the control node; a voltage division unit configured to divide the high voltage supplied to the output terminal to create a division voltage; and an amplification unit configured to amplify a difference between the division voltage of the voltage division unit and a first reference voltage and output an amplified voltage to the second current determination unit, wherein the first current determination unit comprises: a first resistor coupled between the input terminal and the control node; and a first switching element and a second resistor coupled in parallel between the first resistor and the control node, wherein the first switching element couples the first resistor and the control node depending on the voltage of the control node.
