LP2989AIMM-5.0 is a linear voltage regulator for PMIC applications.It provides a cost effective and space tight solution for system voltage regulation from a wide range of input sources, including batteries, photovoltaic cells, AC adapters, and DC power supplies.This device is ideal for low power requirements, such as in stand-by applications.The LP2989AIMM-5.0 operates at a wide input range from 2V to 6V, allowing designers to choose from a variety of input sources, which ultimately reduces component count and Board Size.

The LP2989AIMM-5.0 integrates three circuit blocks in a single device: a voltage reference, an error amplifier, and a series pass element.In normal operation, the voltage reference generates a fixed voltage.This voltage is compared with the regulated output voltage by the internal error amplifier.The output of the error amplifier then controls the on-off status of the series pass element, which regulates the output voltage according to the reference voltage.

Despite its small package size, the LP2989AIMM-5.0 offers the designer several features to improve the design.This device features current limiting, thermal shutdown, and reverse-battery protection, along with low quiescent current and high efficiency.It also operates at a wide output voltage range from 1.5V to 5.0V, allowing for greater flexibility when addressing different requirements.

The LP2989AIMM-5.0 is an ideal solution for a wide range of applications such as cell phones, MP3 players, and personal navigation systems.It is also suitable for space-constrained designs, including portable medical devices, wearable technology, and IoT sensors.In addition, this device provides an easy solution for low power stand-by applications with its low quiescent current, low output voltage tolerance, and reverse-battery protection.

Overall, the LP2989AIMM-5.0 provides the user with the perfect combination of compact size, wide input range, low quiescent current, and high efficiency for low power requirements. By providing all of these features in a single package, the LP2989AIMM-5.0 proves to be a cost-effective solution for a variety of applications.
