The LP2981AIM5X-5.0/NOPB from Texas Instruments is a fixed 5V LDO linear regulator delivering 100mA. With a low quiescent current of 95µA and dropout of 0.37V at full load, it offers efficient power conversion for battery-operated devices. The SOT-23-5 package provides a compact solution, while 63dB PSRR at 1kHz ensures clean output.
- Low Quiescent Current: 95µA extends battery life in portable devices.
- Low Dropout: 0.37V at 100mA maintains regulation near battery end-of-life.
- Good Noise Rejection: 63dB PSRR at 1kHz for sensitive analog circuits.
- Compact SOT-23-5: Saves board space in space-limited designs.
