Abstract
Conventionally, in an electrical device having an output transistor for limiting an input current to produce an output current and a bypass capacitor connected to the output side of the output transistor, the waveform of the current that charges the bypass capacitor cannot be adjusted without varying the capacitance of the bypass capacitor. In an electrical device embodying the invention, the waveform of the current that charges the bypass capacitor can be adjusted by varying the limit value of the output current without varying the capacitance of the bypass capacitor.
