Abstract
Embodiments of the present invention disclose a low dropout regulator and a phase-locked loop. The low dropout regulator includes: a reference voltage source, an error amplifier coupled to the reference voltage source, a regulating circuit, a load coupled to the regulating circuit, a first compensation circuit, and a second compensation circuit. The regulating circuit produces a regulating current under control of a control voltage from the error amplifier. The first compensation circuit is coupled between the error amplifier and the regulating circuit. The second compensation circuit is coupled between an input terminal and an output terminal of the regulating circuit.
