There is disclosed a motor drive circuit, into which an output circuit for supplying a drive output to a motor is incorporated, having a temperature compensating circuit or an output current regulating circuit added to a transistor, interposed between a servo IC for generating a servo signal and the output circuit, for supplying the output circuit with a drive current corresponding to the control output. A dependency on the temperature is obviated by arbitrarily setting an operating point of the output current and compensating temperature characteristics, and the motor is thereby protected from an excessive current.
