Claim 9:
10. A method of frequency compensation in a linear voltage regulator which generates a regulated voltage at an output node from an input voltage received at an input node, said voltage regulator further comprising a load capacitor coupled between said output node of said linear voltage regulator and a first constant reference potential, said method comprising:
sensing a current flowing through a first transistor of a first driver stage coupled between an error amplifier and a pass transistor of said linear voltage regulator, wherein said first transistor is driven by an output of said error amplifier;
adjusting a parameter of a compensation circuit of said linear voltage regulator based on a magnitude of said current,
wherein said adjusting is performed by a compensation adjustment circuit comprising a second transistor, wherein a control terminal of said second transistor is coupled to a control terminal of said first transistor such that said second transistor and said first transistor are in a current-mirror configuration.
