The Torex XC6501A1917R-G is a reliable 200mA LDO regulator providing a fixed 1.9V output. It combines a low quiescent current of 18 µA with a low dropout voltage of 0.47V, making it highly efficient for battery-powered applications. The compact 4-USPN package is perfect for space-constrained designs.

  • High Efficiency: Low 0.47V dropout at 200mA maximizes power conversion efficiency.
  • Low Quiescent Current: 18 µA quiescent current minimizes power loss in idle mode.
  • Small Form Factor: 4-USPN (0.90x1.2) package enables compact product designs.
  • Excellent Ripple Rejection: 50dB PSRR at 1kHz ensures a clean output voltage.
