Features and Applications

The SPX3940T-L-3-3/TR is an Accurate voltage regulator with a low dropout voltage of 280 mV(typical) at 1 A. These regulators are specificallydesigned for low voltage applications that require a low dropout voltage and afast transient response. They are fully fault protected against over-current,reverse battery, and positive and negative voltage transients.

Features:

  • 1% Output Accuracy SPX3940A
  • Guaranteed 1.5 A Peak Current
  • Low Quiescent Current
  • Low Dropout Voltage of 280 mV at 1 A
  • Extremely Tight Load and Line Regulation
  • Extremely Fast Transient Response
  • Reverse-battery Protection
  • Internal Thermal Protection
  • Internal Short Circuit Current Limit
  • Replacement for LM3940
  • Standard SOT-223, TO-220 and TO-263 packages
