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

  • Adjustable power supplies
  • Constant current regulators
  • Audio and video/graphic cards
  • Battery chargers

Distribution Date Description File
07/17/2023 In 2023, MaxLinear will be converting all shipping labels for the parts noted from an EXAR format to MaxLinear’s label. During this transition customers may receive either label. This change affects only shipping and packing labels. This change will not affect the part number, part marking, manufacturing process or manufacturing sites. Only work in progress material will be converted. Existing inventory from MaxLinear’s warehouse, channel sales, distributor, and such, will not be converted. Hence, customers may experience receiving mixed shipments with both Exar and MaxLinear labels for some period until existing inventory of old labels is eventually cleared out. Situation is product to product with no predictable way to determine when all old labels will be exhausted. No change to product form, fit, function and reliability. ADDENDUM A: Fixed MBB label logo for DX204001 to MaxLinear logo. ADDENDUM B: Replaced ‘All other affected products outer box label’ with clearer pictures. Corrected Date Issued (from original PCN) issue date +90 days to August 30, 2023.

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.
