The X11904 is a linear integrated circuit regulator designed to facilitate various applications. Its primary use is to provide a regulated output voltage from an unregulated input voltage, regardless of variations in the input voltage or load current. It can serve as a voltage regulator or a power converter in various systems, including microprocessors, memory systems, and other digital circuits. It has been widely used in the fields of computer communication, digital consumer electronics, and other related industries.

The X11904 is designed to provide a wide range of voltage output levels. It can output both positive and negative voltages, ranging from 2.5V to 18V, making it ideal for use in a variety of microelectronic and digital systems. The linear regulator in the X11904 is also adjustable, allowing it to be easily configured to meet specific regulation requirements. The output of the X11904 is generally stable and consistent, notwithstanding changes in both load and input voltage.

The working principle of the X11904 is a closed loop type. Its linear regulator uses two transistors and two resistors in a negative feedback configuration. The regulator monitors the output voltage, and if it deviates from the required voltage, it adjusts the control signal to the transistors, thus changing their resistance and controlling the output voltage. The regulator consists of two operational amplifiers, one for voltage regulation, and the other for current sensing. The voltage amplifier senses the output voltage, and the current sensing amplifier detects the current through the two transistors, making it possible to maintain the voltage stability.

The X11904\'s regulation accuracy and stability are greatly enhanced by its advanced features. The regulator is equipped with a special thermal shutdown circuit, which is used to prevent the transistors from overheating. It also features an over-current protection circuit which is designed to protect the transistors from excessive current. The regulator also features an automatic power reset circuit which ensures that the output remains in the desired state even if the power is disrupted for a short period of time. This ensures that the output voltage remains within a specified range even after power is restored.

Overall, the X11904 linear regulator features a wide range of applications, reliable regulation, and improved stability. It is an effective power supply solution for a wide range of digital and microelectronic applications. It has proven itself to be a reliable and efficient regulator, ideal for use in many DC supply systems.
