Application Scenarios & Design Considerations

100mA Voltage Regulator

Alternative Part Number

  • LM2936Z-5.0 --: Widely available 5V low-dropout linear regulator in TO-92, functionally similar to HT7550 with good supply and datasheet support.
  • MCP1700-5002E/TO --: Low quiescent current 5V LDO in TO-92 package, suitable drop-in replacement for low-power 5V regulation applications.
  • L78L05ACZ --: Standard 5V linear regulator in TO-92, easy to source and often used where HT7550 5V regulation is required, though dropout is higher.
