Working Principle of IRU1117-18CYTR

IRU1117-18CYTR works on the principle of linear voltage regulation. Linear voltage regulation refers to a process that maintains a steady output voltage by controlling the current that flows through a load. The regulator contains an internal butterfly-type pass element. This element is connected between the input voltage and the output voltage. When the input voltage rises, the current passing through the pass element increases, reducing the output voltage. Conversely, when the input voltage diminishes, the current decreases, increasing the output voltage. A feedback circuit compares the output voltage to an internal reference voltage and adjusts the pass element\'s current accordingly to keep the output voltage at the desired level. This feedback loop provides a stable output voltage. The output voltage can also be adjusted by changing the internal reference voltage, allowing for the implementation of various output voltage schemes.

IRU1117-18CYTR offers several features, such as over-current, over-temperature, and short-circuit protection. These features increase the reliability of the device, making it suitable for use in high-reliability applications.
