Abstract
A power management device includes at least one switching regulator to generate a conversion voltage from an input voltage, a plurality of low drop-out regulators to generate a plurality of output voltages from the conversion voltage, and a controller to estimate drop-out voltages of the low drop-out regulators based on output currents of the low drop-out regulators and to dynamically control the conversion voltage based on the estimated drop-out voltages.
