The LP2988AIMX-3.3/NOPB is a precision low dropout linear regulator delivering a fixed 3.3V output. Capable of sourcing 200mA, it features a low dropout voltage of 0.35V and a quiescent current of just 120 µA, making it highly efficient for battery-operated systems. Its excellent 65dB PSRR at 1kHz ensures clean power for noise-sensitive applications. Housed in a compact 8-SOIC package, this regulator offers a reliable and simple power management solution.
- Extended Battery Life: Ultra-low 120 µA quiescent current minimizes power draw in standby and light-load conditions.
- Clean Power Delivery: 65dB PSRR at 1kHz effectively filters supply noise, ensuring stable operation for sensitive analog and RF circuits.
- High Efficiency at Low Dropout: A 0.35V dropout at 200mA allows operation with minimal headroom, reducing power dissipation.
- Compact and Reliable: The standard 8-SOIC package is widely used and suitable for space-constrained designs.
