    • Disclosed is a low drop-out voltage regulator which can compensate the quick change of an output voltage without using an error amp with regard to the change of the output voltage. A downward output voltage detection part or an upward output voltage detection part is connected between the output voltage and the gate terminal of a power transistor. The downward output voltage detection part senses the decrease of the output voltage and turns on a downward transistor. The voltage of the gate terminal of the power transistor is decreased by the turned-on downward transistor and the output voltage is increased. Therefore, the change of the output voltage is quickly compensated. Also, the upward output voltage detection part countervails the increase of the output voltage.
    • 公开了一种低压差稳压器,其可以补偿输出电压的快速变化,而不使用关于输出电压变化的误差放大器。 在输出电压和功率晶体管的栅极端子之间连接有向下输出电压检测部分或向上输出电压检测部分。 下降输出电压检测部分检测输出电压的降低并接通下行晶体管。 功率晶体管的栅极端子的电压通过导通的下降晶体管而减小,并且输出电压增加。 因此,输出电压的变化被快速补偿。 此外,向上输出电压检测部件反映输出电压的增加。
