Application Scenarios & Design Considerations

Ultra Low Noise, High PSRR, Fast RF, High-Enable, 200mA Low Dropout Regulator

Alternative Part Number

  • LP2985AIM5-2.8 --: Low-dropout linear regulator with 2.8V fixed output in SOT-23-5, similar current capability and pin-compatible footprint, widely available and often used as a direct substitute.
  • MIC5205-2.8YM5 --: 2.8V LDO regulator in SOT-23-5 with comparable dropout and output current, from a different series and manufacturer, suitable as a functional replacement.
  • AP2112K-2.8TRG1 --: 2.8V fixed LDO in SOT-23-5 with low quiescent current and good availability, offering a distinct naming series as an alternative to the original TI part.
  • LP2985AIM5-2.8/NOPB --: Low-dropout 2.8V regulator in SOT-23-5 with similar current capability and pin-compatible layout, widely available and well documented.
  • MIC5205-2.8YM5-TR --: 2.8V LDO in SOT-23-5 with comparable dropout and output current, a common second-source option for small form-factor designs.
