Buck Regulator3A3.3VSwitching Regulator

The LM2576-3.3WT is a high-efficiency 3A step-down switching regulator providing a fixed 3.3V output.

Best for

  • General purpose step-down power conversion
  • Replacing linear regulators for higher efficiency

Avoid if

  • Applications requiring very high switching frequencies (>100kHz)
  • Space-constrained designs where a smaller package is mandatory

Check before use

  • Inductor saturation current rating
  • Diode reverse voltage and current ratings
