Abstract:
A linear voltage regulator is provided having a first transistor connected between a terminal for an input voltage and a terminal for an output voltage, a reference voltage source for producing a reference voltage, a first resistor, a second resistor, a second transistor, wherein the first resistor, the second resistor, and the second transistor are series-connected between the terminal for the output voltage and a reference voltage, and constitute a voltage divider, wherein a divided output voltage is present at a tap of the voltage divider, and also having a differential amplifier with an inverting input and a non-inverting input, wherein the inverting input is connected to the reference voltage source, the non-inverting input is connected to the tap of the voltage divider, and an output terminal of the differential amplifier is connected to a control terminal of the first transistor.
