Abstract
A low dropout voltage regulator for generating an output regulated voltage is provided. The low dropout voltage regulator includes a first transistor and a current recycling circuit. The first transistor has a first terminal for receiving an input supply voltage, a second terminal for generating the output regulated voltage, and a control terminal for receiving a control voltage. The current recycling circuit is configured to drain a feeding current to the second terminal of the first transistor in response to a first signal having feedback information of the output regulated voltage.
