The LP5951MGX-2.8/NOPB is a low-dropout linear regulator from Texas Instruments, delivering a fixed 2.8V output with up to 150mA of current. Its low 55µA quiescent current and excellent PSRR make it suitable for battery-operated and noise-sensitive applications. Housed in a compact SC-70-5 package, this LDO balances performance and size for modern portable electronics.
- Extended Battery Life: Ultra-low 55µA quiescent current minimizes standby power draw.
- Clean Output: 60dB PSRR at 100Hz reduces supply noise for sensitive loads.
- Compact Footprint: SC-70-5 package saves PCB space in miniaturized designs.
- Reliable Regulation: 350mV dropout at 150mA ensures stable operation near battery end-of-life.
