The LP2989AILD-3.3/NOPB is a 500mA low-dropout linear regulator from Texas Instruments, providing a fixed 3.3V output. Its standout feature is a remarkably low quiescent current of just 175 µA, making it ideal for battery-powered applications. With a dropout of 0.65V and 60dB PSRR at 1kHz, it delivers clean, stable power in a compact 8-WSON package.
- Ultra-Low Quiescent Current: 175 µA extends battery life in portable and standby applications.
- High PSRR: 60dB at 1kHz rejects switching noise and RF interference.
- Low Dropout: 0.65V at 500mA allows operation from a 3.95V input, maximizing efficiency.
- Compact Package: 8-WSON (4x4) saves board space in space-constrained designs.
