The XC6220A17BMR-G from Torex is a fixed 1.75V LDO regulator capable of sourcing 1A. With an ultra-low quiescent current of 18μA and dropout of 0.655V at full load, it balances high current with energy efficiency. The SOT-25 package offers a compact solution for power-hungry portable and industrial devices.

  • High output current: 1A supports demanding loads.
  • Ultra-low quiescent current: 18μA minimizes standby power.
  • Low dropout: 0.655V at 1A ensures stable operation.
  • Good PSRR: 50dB at 1kHz for noise rejection.
