Abstract (en)
[origin: DE4442466C1] The unregulated input voltage (U) is introduced via an input connection (1) and the regulated output voltage (VDD) is tapped from an output connection (2). The load current path of a transistor (3) is connected between the input and output connections. The regulated output voltage is fed to a control amplifier (4) whose output is coupled to the transistor's control connection via a capacitor (8). The capacitor is discharged by a current source (7) controlled by the control amplifier. A charge pump (5) has an output for a raised voltage connected to the transistor's control connection and its output voltage is controlled by the control amplifier.
