The Texas Instruments LP5951 is a fixed 3.0V output LDO regulator designed for low-power, battery-operated applications. It delivers up to 150mA with a very low quiescent current of 55 μA. The dropout voltage is only 0.35V at full load, making it ideal for 3.3V to 3.0V conversion. With excellent PSRR of 60dB at 100Hz, it provides clean power for sensitive analog and RF circuits. Available in a compact SOT-23-5 package.
- Ultra-Low Quiescent Current: 55 μA quiescent current maximizes battery life in portable devices.
- Low Dropout: 0.35V dropout at 150mA enables efficient operation from 3.3V rails.
- High PSRR: 60dB at 100Hz filters low-frequency noise effectively.
- Compact Package: SOT-23-5 saves board space in space-constrained designs.
