Abstract
A voltage regulator includes first and second closed-loop amplifiers and a N-type transistor. The first amplifier receives a first reference voltage and a feedback voltage. The second amplifier is responsive to the first amplifier and to the regulated output voltage of the regulator. Both amplifiers are biased by a biasing voltage. The second amplifier has a bandwidth greater than the bandwidth of the first amplifier and a gain smaller that the gain of the first amplifier. The N-type transistor has a first terminal responsive to the output of the second amplifier, a second terminal that receives the input voltage being regulated, and a third terminal that supplies the regulated output voltage. The feedback voltage is generating by dividing the regulated output voltage. An optional fixed or dynamically biased current source biases the first terminal of the N-type transistor. The voltage regulator optionally includes an overshoot correction circuit.
