Abstract
A line driver supplied with a power supply voltage from a power supply uses whole or part of the power supply voltage to generate the output voltage if the input voltage is within a predefined range; loads at least one capacitor with at least one capacitor voltage; and uses whole or part of the at least one capacitor voltage in addition to whole or part of the power supply voltage to generate the output voltage if the input voltage is outside the predefined range.
