METHOD AND DEVICE FOR DECREASING THE VOLTAGE OVER A DISSIPATION-TYPE VOLTAGE REGULATOR

摘要

The invention regards a method and a device for the current feed of a mobile communications device in a device comprising at least one dissipation-type voltage regulator (201), such as a linear regulator, in which the first voltage values of the regulator's input voltage (Vs, 211) is decreased with voltage-decreasing means (202-207, 212) to the second voltage value of the input voltage (Vs) compared to the used voltage (Vbat, 208), which is smaller than the first input voltage, to form the voltage regulator's (201) output voltage (Vout, 209).
