The Torex XC6220A301ER-G is a fixed-output LDO regulator providing a stable 3.0V at up to 1A. With a low quiescent current of 18 μA and 50dB PSRR, it ensures efficient, noise-free operation. The 6-USPC package is ideal for space-constrained applications.

  • Efficient Power Management: 18 μA quiescent current reduces idle power draw.
  • High Output Current: 1A capability supports a wide range of loads.
  • Low Noise: 50dB PSRR at 1kHz ensures clean output for sensitive electronics.
  • Small Size: 6-USPC (1.8x2) package enables compact PCB layouts.

3.3V to 3.0V Conversion

Ideal for powering 3.0V logic and memory from a 3.3V rail, with a low dropout of 0.655V ensuring headroom.

Battery-Powered IoT Modules
