Abstract
Provided is a voltage regulator in which a maximum output current and a short-circuit output current may be accurately set. As a circuit for determining respective current values of a maximum output current (Im) and a short-circuit output current (Is) of an overcurrent protection circuit, the voltage regulator includes a current mirror circuit for mirroring a current in accordance with an output current so as to be capable of current control, without employing a resistor for converting a current into a voltage. Therefore, the maximum output current (Im) and the short-circuit output current (Is) may be accurately set with respect to an output current (Iout).
