The SPX29150/51/52/53 are 1.5A, highly accurate voltage regulators with a low dropout voltage of 390mV (typical) at 1.5A. 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 in the 5-pin versions include enable and error flags.

The SPX29150/51/52/53 is offered in 3-pin and 5-pin TO-220 and TO-263 packages.  For a 3A version, refer to the SPX29300 datasheet.

  • Adjustable output down to 1.25V
  • 1% output accuracy
  • Output current of 1.5A
  • Low dropout voltage of 390mV @ 1.5A
  • Extremely tight load and line regulation
  • Extremely fast transient response
  • Reverse battery protection
  • Zero current shutdown (5-pin version)
  • Error flag signal output for out of regulation state (5-pin version)
  • Standard TO220 and TO263 packages
