    • A regulator circuit is provided which suppresses a variation in output voltage upon occurrence of a variation in input voltage or output current without any increase in steady-state power consumption. The regulator circuit includes a detection circuit and an auxiliary circuit in addition to an error amplifier, an output transistor, a first resistor, a second resistor, and a reference voltage source. The error amplifier, the output transistor, the first resistor, and the second resistor form a typical linear regulator. The detection circuit includes a detecting capacitor, a first transistor, and a gain control resistor, which are serially connected between an input terminal and a ground terminal. A variation in input voltage leads to a change in potential at one end of the detecting capacitor with the input voltage. This causes a transient detecting current to flow, thereby allowing for detecting a voltage variation. The detecting current is amplified in the auxiliary circuit, allowing a feedback current to be fed back to the gate terminal of the output transistor.
    • 提供了一种调节器电路,其在输出电压或输出电流的变化发生时抑制输出电压的变化,而稳定的功率消耗没有任何增加。 除了误差放大器,输出晶体管,第一电阻器,第二电阻器和参考电压源之外,调节器电路还包括检测电路和辅助电路。 误差放大器,输出晶体管,第一电阻和第二电阻构成典型的线性稳压器。 检测电路包括串联连接在输入端子和接地端子之间的检测电容器,第一晶体管和增益控制电阻器。 输入电压的变化导致检测电容器一端的电位随输入电压的变化。 这导致瞬态检测电流流动,从而允许检测电压变化。 检测电流在辅助电路中放大,允许反馈电流反馈到输出晶体管的栅极端。
