Abstract
According to an aspect, a low-dropout (LDO) regulator includes a pre-charge buffer, an output stage, and a noise filter connected between the pre-charge buffer and the output stage of the LDO regulator. The noise filter includes a first resistor. The LDO regulator includes a transistor configured as an input to the output stage, and a compensation circuit connected to an input of the pre-charge buffer. The compensation circuit includes a second resistor. The compensation circuit is configured to provide a compensation current that produces a first voltage drop across the second resistor, where the first voltage drop offsets a second voltage drop produced by an input current of the transistor across the first resistor.
