LP2989AIM-3.0/NOPB TI LDO Regulator | 8-SOIC | 3.0V Fixed Output, 500mA

Product Overview

The LP2989AIM-3.0/NOPB is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments, offering a fixed 3.0V output with a maximum output current of 500mA. Housed in an 8-pin 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 regulation even with minimal input-to-output voltage differential. The LP2989AIM-3.0/NOPB features a shutdown mode that reduces quiescent current to less than 1µA, making it ideal for battery-powered systems. Its wide input voltage range of 2.5V to 16V and excellent line/load transient response make it suitable for a variety of industrial, automotive, and consumer electronics applications.
