LP2989IMX-2.5/NOPB Application Field and Working Principle

Texas Instruments LP2989IMX-2.5/NOPB linear voltage regulator is a type of voltage regulator typically used to power low-noise, low-power, and high-performance systems. This component offers both fixed and adjustable output regulated power, making it an excellent choice for a variety of applications. It has a small package size and a slim profile, so it can easily be mounted in various spaces.

Applications:

• Portable medical devices
• IoT sensing applications
• Battery-operated equipment
• Cell phones, wearables, and other mobile devices
• Networking equipment
• Factory-automated devices and systems

Overview of Working Principle:

The LP2989IMX-2.5/NOPB voltage regulator uses the 3-terminal linear voltage regulator principle. This type of regulator is designed to regulate the output voltage by using a feedback loop, monitoring the output versus a reference voltage. Two outputs are available: the adjustable output voltage and the fixed output voltage.

The adjustable output voltage is set by connecting an external resistor divider to the Adjust pin. The voltage at this external pin sets the output voltage. The fixed output voltage is set by the voltage applied to the Adjust pin.

The LP2989IMX-2.5/NOPB voltage regulator has three onboard protection features which include short circuit protection, thermal shutdown, and reverse polarity protection. It also has an additional output-trim feature which allows the user to change the output voltage by a certain amount.

Conclusion:

The LP2989IMX-2.5/NOPB voltage regulator from Texas Instruments is an ideal solution for a wide range of applications such as portable medical devices, IoT sensing applications, battery-operated equipment, cell phones, and many others. Thanks to its small package size, it can easily be mounted in tight spaces. It also has 3 onboard protection features to ensure that it operates safely and reliably.
