Application Scenarios & Design Considerations

Negative Voltage Regulator

Alternative Part Number

  • L78L30ACZ --: 3.0V fixed linear regulator in TO-92, functionally equivalent to HT7430 with similar dropout and current capability.
  • MC78L30ACP --: 3.0V low-current linear regulator, direct functional replacement for HT7430 in through-hole packages.
  • UA78L30ACLP --: 3.0V fixed positive regulator with comparable specifications, suitable drop-in alternative for HT7430.
  • LM2931AZ-5.0 --: Low-dropout linear regulator with similar 5V-class output and current capability, widely available and pin-compatible in many designs.
  • MC78L05ACPG --: Standard 5V linear regulator in TO-92, common substitute for small Holtek regulator applications with adequate current rating.
  • L78L05ACZ --: Fixed 5V positive voltage regulator in TO-92 package, low cost and broadly stocked, suitable for similar low-current regulation roles.
