The Texas Instruments LP2989ILD-2.5/NOPB is a precision, fixed 2.5V low dropout linear regulator designed for low-power and noise-sensitive applications. It delivers up to 500mA of current while maintaining a low 175 μA quiescent current, making it ideal for battery-powered devices. With a dropout voltage of just 0.65V and excellent PSRR, this regulator ensures a stable and clean output. Its compact 8-WSON package is perfect for space-constrained designs.
- Ultra-Low Quiescent Current: The 175 μA quiescent current extends battery life in portable and standby applications.
- High Accuracy: Provides a precise 2.5V output, ideal for powering sensitive analog and digital circuits.
- Low Dropout Voltage: The 0.65V dropout at 500mA allows for efficient operation with a small input-to-output voltage difference.
- Compact Package: The 8-WSON (4x4) package saves valuable board space in space-constrained designs.
