Abstract:
1. A low dropout voltage regulator (LDO) comprising: a regulating circuit having an input terminal, an output terminal, and a control terminal, said regulating circuit configured to receive an input signal at said input terminal and provide an output signal at said output terminal in response to a control signal received at said control terminal; an amplifier having a first and second input terminal and an output terminal, said first input terminal coupled to a first input path, said output terminal of said amplifier coupled to said control terminal of said regulating circuit via a path to provide said control signal; a first compensating path coupled between a first node on said first input path and a first node on said path coupling said output terminal of said amplifier to said control terminal of said regulating circuit, said first compensating path comprising a first compensating capacitor; and a second compensating path coupled between said output terminal of said regulating circuit and a second node on said path coupling said output terminal of said amplifier to said control terminal of said regulating circuit, said second compensating path comprising a second compensating capacitor.
