Application Scenarios & Design Considerations

0.5A MAX CONSTANT CURRENT LED DRIVER

Alternative Part Number

  • AL5809-15P1-7 --: Constant-current LED driver in a similar SOT-25/SOT-23 package with comparable current capability, suitable as a functional replacement for the STCS05DR.
  • BCR421U --: Linear LED current controller with adjustable current setting, offering similar constant-current sink behavior and a small SOT-23 style footprint.
  • NSI45020AT1G --: Two-terminal constant-current regulator rated around 20 mA, usable in LED current-limiting applications similar to the STCS05DR with simple biasing.
