The LP2981IM5X-3.0/NOPB is a series of high-performance integrated circuits with low external component count and excellent PSRR, from Texas Instrument’s Adaptive Regulators family. An important application of this series is to provide a regulated output voltage of a power supply with a high load current.

The integrated circuit of the LP2981IM5X-3.0/NOPB includes two linear regulator stages. The first stage is responsible for providing a stable and highly regulated output voltage with very low output noise. The second stage is typically used to limit the current through the load by generating a voltage source, which can be adjusted in small increments. This adjustability allows a high degree of accuracy in the regulation of the output voltage of a power supply.

The output voltage of the LP2981IM5X-3.0/NOPB is regulated via an internal reference voltage, which is adjusted using an external resistor divider circuit. This divider circuit is used to adjust the reference voltage, which in turn controls the output voltage of the regulator. The reference voltage is also regulated by an internal temperature compensation circuit to ensure that the output voltage is stable over temperature changes.

The LP2981IM5X-3.0/NOPB also includes a current-limit circuit, which prevents excessive current flowing through the load. This current-limit circuit is adjustable using an external resistor, allowing the user to set the maximum current that can flow through the load. Additionally, the LP2981IM5X-3.0/NOPB contains an over-voltage protection circuit, which will shut down the power supply if the output voltage exceeds a set limit.

The LP2981IM5X-3.0/NOPB is highly efficient and reliable, and is designed for applications such as telecom and computing systems, as well as automotive, industrial and consumer electronics. The device can be used in a wide range of applications, including portable electronic devices, digital cameras, supervisory circuits, notebook computers, and office equipment.

The LP2981IM5X-3.0/NOPB is a versatile linear regulator and is suitable for a wide range of applications. The device is highly efficient and offers excellent PSRR, making it an ideal solution for high-load current applications. The integrated circuit is reliable, simple to use and offers a wide range of features and benefits, making it a great choice for many different applications.
