Abstract (en)

[origin: EP1253498A1] The device has an output voltage dependent on the control of a transistor within the regulator and a stabilizing device that can vary the current flowing through the transistor. The current flowing through the transistor can be varied by varying the load driven by the transistor. The load driven by the transistor can be varied by reconfiguring the voltage regulator.
