Low-dropout voltage stabilizing system and control method thereof

The invention provides a low-dropout voltage stabilizing system. The low-dropout voltage stabilizing system comprises a low-dropout voltage stabilizer. The comparison circuit generates a comparison voltage according to a reference voltage and a feedback voltage. The amplification circuit generates an amplification voltage according to the comparison voltage. The transistor receives an input voltage and is controlled by the amplification voltage to generate an output voltage at an output end. The first resistor is coupled between a first node and a ground terminal. The feedback voltage is generated at the first node. The second resistor is coupled between the output end and the first node. At a starting time point of the low dropout regulator, the second resistor has a first resistance value. After the input voltage reaches a maximum voltage, the second resistor has a second resistance value. The second resistance value is greater than the first resistance value. 本发明提供一种低压差稳压系统，其包括一低压差稳压器。比较电路依据一参考电压以及一反馈电压产生一
