PURPOSE: A variable output voltage adjustment device is provided to arbitrary adjust the output terminal of a low-dropout voltage regulator(LDO) by adding a serial variable resistor and a parallel variable resistor, thereby supplying an optimized output voltage to the mobile phone system. CONSTITUTION: A variable output voltage adjustment device includes a power source(210), a Low-Dropout Voltage Regulator(LDO)(220) and a voltage divider(230). The power source(210) applies the voltage, and the LDO(220) stabilizes the voltage applied from the power source(210) to apply the stabilized voltage to the voltage divider(230). The voltage divider(230) mounted thereon the variable resistor adjusts the voltage applied from the LDO(220) to output the adjusted voltage.
