LP2989IMX-5.0/NOPB TI LDO Regulator | 8-SOIC | 5.0V Output, 500mA

Product Overview

The LP2989IMX-5.0/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, offering a fixed 5.0V output with a maximum current of 500mA. Housed in an 8-SOIC package, this device is designed for noise-sensitive applications requiring low quiescent current and high accuracy. With a dropout voltage of only 310mV at full load, it ensures efficient operation even with minimal input-to-output voltage differential. The LP2989 features a shutdown mode that reduces quiescent current to less than 1μA, making it ideal for battery-powered systems. Its output voltage accuracy is ±1.5% over line, load, and temperature variations, providing a stable power supply for critical loads.
