Application Field

The LP3982ILDX-1.8 is designed to provide an adjustable output current up to 1.8A. It is suitable for applications such as powering microprocessors, LCD backlight drivers, linear voltage regulator powering, and other mobile devices.

The LP3982ILDX-1.8 is ideally suited for applications that require ultra-low power consumption, high efficiency and low operating temperatures. Its output voltage is adjustable from 5V to 7V, making it suitable for powering a variety of devices.

Working Principle

The LP3982ILDX-1.8 is an adjustable linear voltage regulator. It works by providing a constant output current (1.8A) regardless of input voltage or load current. It also features a low output voltage deviation and low power consumption.

The device works by using a resistor ladder to adjust the output voltage. The input voltage is divided by the resistance of the ladder until the desired voltage is achieved. The output voltage is then monitored and adjusted accordingly by the on-board microcontroller.

The device also features a thermal shutdown circuit to prevent overheating. When the temperature rises above a certain threshold, the device will cut off the output current to protect itself from damage.

The LP3982ILDX-1.8 is designed to be low power consumption, efficient, and low operating temperature. Its adjustable output voltage and thermal shutdown circuit make it an ideal choice for a wide range of applications.
