Alternative Part Number

  • LM1117DT-3.3 --: Widely available 3.3V low-dropout linear regulator in TO-252/DPAK, functionally similar to the IRU1120 with good pin compatibility and broad second-source support.
  • AMS1117-3.3 --: Low-cost 3.3V LDO regulator in SOT-223/TO-252, commonly used as a drop-in replacement for IRU1120-type regulators in many designs.
  • LD1117DT33 --: ST's own 3.3V LDO regulator in DPAK, same manufacturer family and package style, offering a familiar alternative with similar electrical characteristics.
  • LM1117-ADJ --: Widely available adjustable low-dropout linear regulator with similar current capability and pinout, a common drop-in replacement for the IRU1120.
  • AMS1117-ADJ --: Low-cost adjustable LDO regulator with comparable voltage and current ratings, frequently used as a substitute in similar applications.
  • LT1085 --: Adjustable linear regulator with higher current capability and robust performance, suitable when extra margin is needed.
