The LP2985AIM5X-2.5 is suitable for use in a wide range of applications including notebooks, telecommunication equipment, automotive applications, lighting and consumer electronics. The excellent performance of the voltage regulator supports current limiting, over temperature protection and extended battery life. The adjustable or fixed output options of the LP2985AIM5X-2.5 make it suitable for a range of applications where it is needed to set the exact desired voltage. The low quiescent current characteristics of the voltage regulator make it a great solution for battery-powered devices.

Working Principle of LP2985AIM5X-2.5

The LP2985AIM5X-2.5 is an adjustable or fixed voltage linear voltage regulator. It works by taking a higher input voltage and reducing it to a lower output voltage. This is done by passing current through an internal series resistor. As the current passes through the resistor, it is reduced from the input to the output. The output voltage is then regulated by varying the series resistance. This is done by the integrated feedback loop, which keeps the output voltage at the desired level depending on the output voltage setting. The linear voltage regulator also includes several protection features, like short circuit protection and current limit protection, which protect the device from over current situations.
