ABSTRACT:
Voltage regulator for providing an output voltage (Vout) to a load (Zload) having an output transistor (T1), an operational amplifier (OA), and a first reference voltage source (VS). The negative input of the operational amplifier (OA) is connected to a feedback line (FL) to receive an input voltage derived from the output voltage. The first reference voltage source (VS) provides a reference voltage (Vref) to the positive input (IN2) of the operational amplifier (OA). The output (O1) of the operational amplifier (OA) is connected to a floating voltage source (FVS; C1). The other side of the floating voltage source is connected to a gate terminal (G) of the output transistor (T1). The floating voltage source (FVS) provides a voltage level (Vg) at the gate terminal of the output transistor (T1) higher than the output voltage of the operational amplifier (OA).
