Alternative Part Number

  • TPS1406ACTS --: Similar low-dropout linear regulator in the same package family with comparable voltage and current ratings, widely available and pin-compatible in most designs.
  • LM1406ACTS --: Alternative LDO regulator offering similar electrical characteristics and package compatibility, suitable as a drop-in replacement after verifying pinout.
  • MIC1406ACTS --: Comparable linear regulator with similar output voltage and current capability, usable as a functional substitute with minor layout verification.
  • LM317LZ --: Widely available adjustable linear regulator in TO-92 that can serve as a functional substitute in many low-current regulator applications.
  • TL431ACLP --: Adjustable shunt regulator in TO-92, commonly used as a drop-in replacement for programmable reference/regulator functions.
  • LM317T --: Standard adjustable positive voltage regulator in TO-220, higher current capability and broad availability as an alternative regulator solution.
