The Torex XC6220A251MR-G is a fixed-output, low dropout linear regulator delivering a stable 2.5V supply. It supports up to 1A of load current with a dropout voltage of just 0.655V at full load. Its low 18 μA quiescent current and 50dB PSRR make it an efficient, noise-immune choice for battery-powered and portable devices. Housed in a compact SOT-25 package, it is designed for space-constrained applications.

  • Extended Battery Life: Ultra-low 18 μA quiescent current minimizes standby power draw.
  • High Current Capacity: Delivers up to 1A, suitable for powering demanding loads.
  • Clean Power Output: 50dB PSRR at 1kHz filters supply noise for sensitive electronics.
  • Compact Footprint: SOT-25 package saves valuable PCB space.
