LP2989AIMX-3.3/NOPB TI LDO Regulator | 8-SOIC | 3.3V Output, 500mA

Product Overview

The LP2989AIMX-3.3/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, offering a fixed 3.3V 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 typically 310mV at full load, it ensures efficient operation even with low input-to-output voltage differentials. The LP2989AIMX-3.3/NOPB features a shutdown mode that reduces quiescent current to less than 1µA, making it ideal for battery-powered systems.
