Working Principle

ISL80103IR25Z employs a Linear Regulation (LDO) topology to provide precise voltage regulation even at low current levels. It uses a series of transistors to regulate the output voltage and an internal reference, which helps maintain the required level of accuracy. The output voltage is determined by the reference voltage, which is set by the user. The reference voltage is compared with the voltage input from the load, and the difference is used to control the voltage output.

The device also has a built-in current limit protection, which helps protect it from over current events. It is also designed with temperature compensation, which prevents it from heating up during power-up and power-down cycles. When the device is in thermal shutdown, the output voltage is reduced and the device is turned off until the temperature returns to a normal range.

Finally, the device has built-in overvoltage protection, which helps protect against overvoltage conditions and provide stable operation over a wide input voltage range. The overvoltage protection helps protect the device and the system from damage due to excess voltage levels.
