Abstract

1380761 Electricity supply regulation ATES COMPONENTI ELETTRONICI SpA 16 Feb 1972 [25 Aug 1971] 7135/72 Heading G3X An integrated circuit power supply includes a series transistor voltage stabilizer and an arrangement for producing an output voltage which increases with load current, i.e. a negative resistance characteristic. In the system shown, the impedance of a transistor To is controlled by a circuit C (not detailed) in order to regulate a voltage V 0 appearing between terminals 2, 3 of an integrated circuit CI. A second transistor T 1 is constructed so that it passes a current proportional to the collector current of transistor T 0 , and is connected so as to control the output current of a current mirror T 2 , T 3 . This current, which is proportional to the current carried by transistor To, is fed to terminal 3 forming the connection between resistors R a , R b which comprise a voltage divider across the output supply V out . It is shown that the voltage V out increases linearly with the output current I out . The system may be used to supply a small D.C. motor.
