Abstract
The present technology includes a regulator. The regulator includes an input circuit connected between first and second sub circuits connected to an output circuit and a charging circuit. A first feedback path between the output circuit and the second sub circuit is configured to feed back an output voltage as a first feedback voltage and output a sub voltage in response to the first feedback voltage. A second feedback path between the output circuit and the input circuit is configured to feed back the output voltage as a second feedback voltage and output a first divided voltage in response to the second feedback voltage.
