Application Scenarios & Design Considerations

General Purpose Regulator

Alternative Part Number

  • AP7231 --: Similar low-dropout linear regulator with comparable output voltage and current rating, widely available and pin-compatible in many designs.
  • LM317 --: Adjustable linear regulator that can be configured to the same output voltage, very common and robust alternative for general-purpose regulation.
  • AMS1117-3.3 --: Fixed 3.3V LDO regulator with similar current capability, low cost and broad availability, suitable for many Holtek HT7231 applications.
  • LM7231 --: Standard fixed-output LDO regulator family offering equivalent output voltage and current capability, with broad availability and established reliability.
  • SGM2036 --: Low-noise CMOS LDO regulator with comparable dropout and current specifications, suitable for replacing Holtek HT7231 in many applications.
