ABSTRACT:
A voltage regulator exhibits a load line that is piecewise linear. This piecewise linearity variation has a first constant voltage segment VLEAKat which output voltage is regulated for output currents less than or equal to the leakage current IL. The output voltage VLEAKcorresponds to the maximum output voltage allowable at the leakage current for a given operational range specification. The piecewise linearity variation further includes a second, linearly decreasing segment that varies from the maximum allowable output voltage VLEAKat the leakage current to a full load voltage VDROOPat full load current IFL. This serves to effectively maximize the available output voltage swing in the presence of a leakage current offset. The piecewise linear load line is adjustable to accommodate changes in leakage current.
