Low-profile power supply regulator utilizing flipped voltage follower

A voltage regulator, comprising:

• a first transistor, wherein a source of the first transistor is coupled to a supply rail, and a drain of the first transistor is coupled to an output of the voltage regulator;
• a second transistor, wherein a source of the second transistor is coupled to the output of the voltage regulator, and a drain of the second transistor is coupled to a gate of the first transistor via a feedback path;
• a first current source coupled to the drain of the second transistor;
• a second current source;
• a third transistor, wherein a gate of the third transistor is coupled to the output of the voltage regulator, and a source of the third transistor is coupled to a ground;
• and
• a resistor coupled between a drain of the third transistor and the second current source, wherein a gate of the second transistor is coupled between the resistor and the second current source.
