Application Scenarios & Design Considerations

500 mA, Low-Noise LDO Voltage Regulator

Alternative Part Number

  • LP2985AIM5-2.5 --: Low-dropout 2.5V linear regulator in SOT-23-5 with similar 150mA output and low quiescent current, a common drop-in style replacement for the SPX3819.
  • MIC5205-2.5YM5 --: 150mA low-noise LDO regulator with 2.5V fixed output in SOT-23-5, closely matching the SPX3819's current and voltage ratings.
  • LM1117S-2.5 --: Widely available 2.5V fixed LDO in SOT-223 with higher 800mA current capability, suitable when extra headroom on load current is acceptable.
