Abstract
A voltage regulator circuit produces a voltage reference with high line rejection even for low values of the supply voltage. The regulator is of the type that produces a regulated voltage value for a bandgap voltage generator and includes a regulation circuit portion and a reference circuit portion. The regulation circuit portions is supplied with the supply voltage and has an output at which the regulated voltage value is produced and an input that receives a voltage reference. The reference circuit portion produces the voltage reference and includes a first circuit leg that receives the supply voltage through a controlled switch and a second circuit leg that receives the regulated voltage value.
