According to a voltage regulator of the present device, a drive IC and an output transistor are formed separately, and the drive IC is mounted on the ground lead and connected electrically to an input lead. The output transistor is mounted on an output lead and connected to the drive IC and to the input lead. As such, the leads, the drive IC and the output transistor are arranged as a package so that the regulator can accomodate various output voltage or current, and it is not necessary to specially make a number of drive ICs which have different output current levels respectively so that the number of masks is reduced. Due to the fact that the output transistor is separated from the drive IC, the size of the drive IC chip is made smaller, thereby reducing the manufacturing costs.
