The Texas Instruments LP2989IMM-3.0/NOPB is a fixed 3.0V low dropout linear regulator capable of delivering 500mA. With a low quiescent current of 175 μA and a dropout voltage of just 0.65V at full load, it is engineered for efficiency in battery-operated systems. Its 60dB PSRR at 1kHz ensures clean, stable power for sensitive electronics. Housed in a compact 8-VSSOP package, this regulator balances performance and footprint for modern PCB designs.
- Extended Battery Life: Ultra-low 175 μA quiescent current minimizes standby power draw.
- High Ripple Rejection: 60dB PSRR at 1kHz filters noise for sensitive analog loads.
- Low Dropout: 0.65V dropout at 500mA maintains regulation near end-of-battery voltage.
- Compact Footprint: 8-VSSOP package saves board space in dense designs.
