LOW DROP-OUT VOLTAGE REGULATOR

摘要

A system including a first transistor, a first capacitor and a circuit. The first transistor has a first control input and is configured to regulate an output voltage. The first capacitor is coupled at one end to the first control input and at another end to a circuit reference. The circuit is configured to provide a first voltage to the first control input, where the first voltage includes an offset voltage that is referenced to the output voltage and adjusted to compensate for variations in the first transistor.
