ABSTRACT:
An electronic device (100) includes a regulator (102) for generating an operating voltage. The device (100) also includes at least one component (110) using the operating voltage and requiring a minimum input voltage for proper operation. The device (100) further includes a sensor (115) for sensing the minimum input voltage of the component (110) to produce a minimum operating voltage. Also included in the device (100) is a feedback circuit (116), responsive to the sensor (115), for feeding the minimum operating voltage to the regulator (102) whereby the regulator (102) alters the output voltage to the level of the minimum operating voltage.
