LP2989AILD-3.0/NOPB TI LDO Regulator | 8-WSON(4x4) | 3.0V Output, 500mA

Product Overview

The LP2989AILD-3.0/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 3.0V output with a maximum current of 500mA. Housed in an 8-pin WSON package (4x4mm), this device offers excellent line and load regulation, low noise, and fast transient response, making it ideal for noise-sensitive applications such as RF, analog, and mixed-signal circuits. The NOPB suffix indicates a lead-free (RoHS-compliant) package.
