Abstract
A low dropout voltage regulator circuit with non-Miller frequency compensation is provided. The circuit includes an input voltage terminal; an output voltage terminal; an error amplifier having a first input coupled to a reference voltage; a voltage follower coupled to an output of the error amplifier; a pass device; and a feedback network. An input terminal of the pass device is coupled to the input voltage terminal. A control terminal of the pass device is coupled to an output of the voltage follower. An output terminal of the pass device is the output voltage terminal. The feedback network includes two resistors in series between the output voltage terminal and ground. A node between the resistors is coupled to a second input of the error amplifier. A frequency compensation capacitor also is coupled between the output voltage terminal and the node.
