The LM1117MPX-25NOPB is a fixed 2.5V low dropout linear regulator capable of delivering 800mA. Its 1.2V dropout voltage allows efficient operation from 3.3V or 3.7V rails. With 68dB PSRR at 120Hz and 10mA quiescent current, it suits noise-sensitive applications. The SOT-223 package enables compact PCB layouts with good thermal dissipation.
- High output current: 800mA capacity supports demanding digital loads while maintaining regulation.
- Low dropout: 1.2V at full load enables operation from lower input rails, reducing power dissipation.
- Excellent ripple rejection: 68dB PSRR at 120Hz filters mains-frequency noise for clean output.
- Compact SOT-223 package: Small footprint with exposed pad for thermal management.
