Claim 1
Independent Claim
108 words
In a transistorized voltage regulator comprising, a transistor having a collector electrode connected to an input terminal, an emitter electrode connected to an ouput terminal and a base electrode connected to said input terminal through means for providing a constant current, and means including a zener diode connected between the base of said transistor and ground for regulating the voltage to the base of said transistor, the improvement comprising: a first output terminal connected to said emitter electrode for supplying regulated voltage to a high-power dissipation load; and a second output terminal connected to the base of said transistor for supplying regulated voltage to a low-power dissipation load.
