The SPX29501/02 are 5A, highly accurate voltage regulators with a low dropout voltage of 420mV at 5A. These regulators are specifically designed for low voltage applications that require a low dropout voltage and a fast transient response. They are fully fault protected against overcurrent, reverse battery and positive and negative voltage transients. On-Chip trimming adjusts the reference voltage to 1% initial accuracy. Other features include enable and error flags.

The SPX295001/02 are offered in 5-pin TO-220 and TO-263 packages. For a 1.5A version, refer to the SPX29150 datasheet. For a 3A version, refer to the SPX29300 datasheet.

  • 5.0V and 3.3V at 150mA output
  • Accurate: 0.5% for SPX29501A
  • Very low quiescent current
  • Low dropout voltage: 300mV at 150mA
  • Extremely tight load and line regulation
  • Very low temperature coefficient
  • Current and thermal limiting
