摘要： A voltage regulator according to the present invention is operated stably. Regardless of a condition of a load (25), a variation in drain voltage of a PMOS transistor (34) is made equal to a variation in output voltage (Vout) at an output terminal of the voltage regulator. Then, a variation in voltage which is equal to the variation in output voltage (Vout) at the output terminal which is caused by a change of the condition of the load (25) is fed back to an error amplifier (70), so a gain of a signal for phase compensation which is fed back to the error amplifier (70) is determined based on the output voltage (Vout). Therefore, even when the condition of the load (25) changes, the behavior of phase compensation is correct.
摘要翻译：根据本发明的电压调节器稳定地工作。不管负载条件（25）如何，使PMOS晶体管（34）的漏极电压的变化等于电压调节器的输出端的输出电压（Vout）的变化。然后，由负载（25）的状态的变化引起的等于输出端子的输出电压（Vout）的变化的电压变化被反馈到误差放大器（70），因此，基于输出电压（Vout）来确定反馈到误差放大器（70）的相位补偿信号的增益。因此，即使负载（25）的状态发生变化，相位补偿的动作也是正确的。

摘要： Provided is a voltage regulator capable of performing appropriate phase compensation. Even when a difference between an input voltage and an output voltage is small, an appropriate phase compensation voltage based on an output voltage (Vout) is generated in a resistor circuit (19), and the appropriate phase compensation voltage is applied to a phase compensation capacitor (20). Accordingly, the voltage regulator is capable of performing appropriate phase compensation.
