Abstract
A low dropout (LDO) includes voltage inputs to receive input from voltage sources. The LDO voltage regulator includes a regulated voltage output, blocking diodes, and circuitry configured to block leakage from a first voltage input with a first blocking diode when the first voltage input is less than the regulated voltage output, and to provide the regulated voltage output from the first voltage input and a second voltage input.
