<p>The disclosed semiconductor voltage regulator comprises an NPN power transistor connected to a field coil of a battery charging AC generator and turned on and off through an NPN control transistor under the control of a Zener diode, a suppression diode for the field coil, and passive elements. The transistors especially including the power transistor and diodes without or with resistors form an integrated semiconductor element on a semiconductor substrate while the passive elements form a hybrid thick film integrated circuit on a ceramic substrate. The integrated element may be disposed on the ceramic substrate underlaid with a heat sink or directly on the heat sink.</p> |
