Application Scenarios & Design Considerations

Multiple voltage regulator with switch and ignition buffer

Alternative Part Number

  • TDA3681J --: Same TDA3681 voltage regulator family from the original Philips semiconductor business (now NXP), with comparable multi-output regulator function and similar pinout, making it the closest functional substitute.
  • TDA3683J --: Related NXP multi-output voltage regulator in the same TDA368x series, offering similar supply outputs for car radio/audio applications and often used as a drop-in upgrade.
  • L4979D --: Alternative multi-output automotive voltage regulator from a different manufacturer and series, providing comparable regulated outputs and suitable as a cross-vendor replacement when the NXP parts are unavailable.
