Abstract
A voltage regulator with an input terminal to be coupled to an input voltage source and an output terminal to be coupled to a load. The voltage regulator has a first switch to intermittently couple the output terminal to the input terminal, a voltage sensor to detect a voltage at the output terminal, a current sensor to detect a current flowing along a circuit path between the input terminal and the output terminal, and a controller connected to the switch, the voltage sensor and the current sensor. The controller is configured to close the first switch if the voltage is less than a first threshold voltage and the current is less than a first threshold current, and the controller is configured to open the first switch if the voltage is greater than a second threshold voltage and the current is greater than a second threshold current.
