Abstract: A voltage regulator is arranged to receive an input voltage (Vin) and produce a regulated output voltage (Vout) and comprises: a current source transistor (Msource) and a current sink transistor (Msink) arranged to provide the output voltage at a node therebetween; a first error amplifier; and a second error amplifier. The first error amplifier is arranged to apply a first control voltage to the gate terminal of the current source transistor, wherein the first control voltage is dependent on the difference between the feedback voltage (Vfb) and the reference voltage (Vref). The second error amplifier arranged in parallel to the first error amplifier, the second error amplifier being arranged to apply a second control voltage to the gate terminal of the current sink transistor, wherein the second control voltage is dependent on the difference between the feedback voltage and the reference voltage. The feedback voltage is derived from the output voltage.
