Abstract
A dual input single output (DISO) regulator, includes a comparator configured to receive a first and second power supply signal and to provide a first compared signal; a first switch configured to couple the first power supply source to an intermediate node, and a second switch configured to couple the second power supply source to the intermediate node; a control logic circuit, coupled to the first comparator, to the first switch, and to the second switch, and configured to receive the compared signal to control the first and the second switch in a first and second operating condition based on the compared signal. The intermediate node being biased by an intermediate power supply signal correlated to the first or second power supply signal. The DISO regulator includes a low-dropout regulator, configured to provide a regulated power supply signal based on the intermediate power supply signal.
