Abstract
A tunable voltage regulator has an output generating a variable voltage and an input that receives a trimming signal for controlling the output variable voltage. A current regulating circuit operates to regulate a current flowing through a load in response to the variable voltage. A control circuit senses the variable voltage and a drop voltage of the current regulating circuit, and determines whether the current regulating circuit has failed to regulate the current flowing through the load because the variable voltage is too low. In response thereto, the control circuit generates the trimming signal to set the variable voltage to a value sufficient for the current regulating circuit to successfully regulate the current flowing through the load.
