Application Scenarios & Design Considerations

Triple Low Dropout Regulator Controllers

Alternative Part Number

  • LM1117MP-3.3/NOPB --: Widely available low-dropout linear regulator in SOT-223 with similar 3.3V fixed output and current rating, a common drop-in replacement for Semtech SC1112 series regulators.
  • AMS1117-3.3 --: Low-cost 3.3V LDO regulator in SOT-223 with comparable dropout and load capability, frequently used as a substitute for SC1112TS.TR in many designs.
  • MIC5219-3.3YM5-TR --: Low-dropout 3.3V regulator with similar electrical characteristics and small package, suitable when a different vendor and series is preferred over the Semtech part.
