The XRP29302 is a 3A, highly accurate voltage regulator with a low dropout voltage of 600mV (typical) at 3A.

This regulator is specifically designed for low voltage applications that require a low dropout voltage and a fast transient response. It is fully fault protected against overcurrent, reverse battery, and positive and negative voltage transients. On-chip trimming adjusts the reference voltage to 1% initial accuracy.

The XRP29302 is offered in 5-pin TO220 and TO263 packages.

  • 3A guaranteed output current
  • Low dropout voltage of 600mV @ 3A
  • Adjustable output down to 1.25V
  • 1% output accuracy
  • Tight load and line regulation
  • Fast transient response
  • Reverse battery protection
  • Zero current shutdown
  • Drop-in replacement to SPX29302
  • Lead free 5-pin TO220 and TO263 Packages

The reason for R2 value being a minimum of 10kOhms is to prevent an unwanted latch up condition if the ADJ pin is exposed to high levels of current. Please keep in mind that a minimum output load current of 5mA is still required for maintaining regulation.
