ABSTRACT:
A voltage regulator with a very low drop-out voltage. The regulator utilizes an inversely biased metal-oxid semiconductor field effect transistor as a regulating element. The field effect transistor is linearly controlled by an error amplifier which compares the regulated output with a reference voltage. The field effect transistor creates a voltage drop between the input and the regulated output by a diode function within the field effect transistor. The field effect transistor bypasses this diode function with a linearly controlled resistance function to thereby create a regulated output.
