Low-voltage linear adjuster

A voltage regulator of low voltage linear type consists of an error amplifier with its reverse phase input end being connected to a reference voltage source, a p type of power tube with its grid being connected to output end of said amplifier and its drain electrode being used as output end of said voltage regulator, a dynamic control unit with its input end being connected to the same phase input end of said amplifier and its output end being connected to grid or drain electrode of power tube. Its regulating method is also disclosed.
