    • A series regulator with an over current protection circuit regulates output current by controlling an output transistor. A current sense transistor output depends on the conductivity of the output transistor. A current limiting transistor controls the conductivity of the output transistor. A current supply provides current to a constant current source and a converter output of a current to voltage converter. The converter output is connected to a control electrode of the current limiting transistor. A first differential transistor couples the current sense transistor to the constant current source and a second differential transistor couples the current supply to the constant current source. The current sense transistor controls the second differential transistor to vary a control current. When the control current matches a threshold value, the current limiting transistor limits maximum current flow through the output transistor.
    • 具有过流保护电路的串联调节器通过控制输出晶体管来调节输出电流。 电流检测晶体管输出取决于输出晶体管的电导率。 限流晶体管控制输出晶体管的导电性。 电流源提供电流到电流到电压转换器的恒定电流源和转换器输出的电流。 转换器输出连接到限流晶体管的控制电极。 第一差分晶体管将电流检测晶体管耦合到恒流源,第二差分晶体管将电流源耦合到恒流源。 电流检测晶体管控制第二差分晶体管以改变控制电流。 当控制电流与阈值匹配时,限流晶体管限制通过输出晶体管的最大电流流动。

    • A power switch circuit includes a first switch transistor connected to a main power supply, which supplies a first voltage, a second switch transistor connected in series to the first switch transistor and to a backup power supply, which supplies a second voltage. A switch control unit controls activation and deactivation of the first and second switch transistors so that either one of a voltage corresponding to the first voltage and a voltage corresponding to the second voltage is selectively output to a connection node between the first and second transistors. The first switch transistor includes a first diode, which is formed so that a direction from the main power supply toward the connection node defines a forward direction, and a second diode, which is formed so that a direction from the connection node toward the backup power supply defines a forward direction.
