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

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.
