Application Scenarios & Design Considerations

Low Dropout Linear Voltage Regulator

Alternative Part Number

  • LM2940CT-5.0 --: Widely available 5V low-dropout linear regulator in TO-220, similar current capability and function as a drop-in style replacement.
  • L4949EP --: Automotive-grade 5V LDO regulator with comparable input voltage range and load capability, suitable for similar automotive supply applications.
  • MC7805CD2TR4G --: Standard 5V linear regulator in D2PAK, common and cost-effective alternative when dropout requirements are less critical.
