Application Scenarios & Design Considerations

General Purpose Regulator

Alternative Part Number

  • HT7550-1 --: Same Holtek linear regulator family with 5V fixed output and similar SOT-89 package, making it a close functional drop-in for HT7250 applications.
  • LM78L05ACZ --: Industry-standard 5V fixed linear regulator in TO-92, widely available and electrically compatible for general HT7250 replacement.
  • MC78L05ACPG --: Common 5V low-current linear regulator with similar ratings and pinout, suitable as a second-source alternative when Holtek parts are unavailable.
  • LM317L --: Widely available adjustable linear regulator in a similar low-current class, easy drop-in for many HT7250 applications with well-documented specs.
  • TL317 --: Adjustable positive voltage regulator comparable to the HT7250, with broad availability and similar electrical characteristics.
  • LM317 --: Industry-standard adjustable regulator that can substitute the HT7250 in most circuits, though it comes in a larger package with higher current capability.
