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 the J package variant; closest functional match and drop-in compatible in most applications.
  • TDA3683J --: Related NXP multi-output voltage regulator in the same TDA368x series with similar supply and output characteristics, suitable as a functional substitute where minor pin differences are acceptable.
  • L4970A --: Alternative multi-output regulator IC from a different manufacturer and series, offering comparable voltage regulation capability for automotive/industrial supply designs when the original is unavailable.
