Abstract
Provided is a voltage regulator including an overcurrent protection circuit, which does not need a test circuit. The voltage regulator has a configuration in which a reference voltage circuit includes an element that determines a reference voltage and an overcurrent protection circuit includes an element that determines a maximum output current, the element of the reference voltage circuit and the element of the overcurrent protection circuit having the same characteristics. Accordingly, there is a correlation between an output voltage before trimming and the maximum output current for overcurrent protection. Thus, a maximum output current before trimming can be estimated without performing evaluation by a test circuit.
