LP2989AIMM-5.0/NOPB TI LDO Regulator | 8-VSSOP | 5.0V Output, 500mA

Product Overview

The LP2989AIMM-5.0/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, offering a fixed 5.0V output with a maximum output current of 500mA. Housed in a compact 8-VSSOP 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 small input-to-output voltage differentials. The LP2989AIMM-5.0/NOPB features a wide input voltage range from 2.2V to 16V, making it suitable for a variety of power supply designs. Its low output noise (30µVrms typical) and high PSRR (60dB at 1kHz) make it ideal for powering analog and RF circuits.
