- Thermal shutdown and current limit protection  
- Small SOT-23-5 package for space-constrained designs  

This information is based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

500mA, Low-Noise LDO Voltage Regulator

Alternative Part Number

  • LP2985AIM5-3.0 --: Low-dropout 3.0V linear regulator in SOT-23-5 with similar 150mA output and low noise, a common drop-in replacement for the SPX3819.
  • MIC5205-3.0YM5 --: 150mA LDO regulator in SOT-23-5 with 3.0V fixed output and low dropout, functionally equivalent and widely available.
  • AP2112K-3.0TRG1 --: 600mA CMOS LDO in SOT-23-5 with 3.0V output, offers higher current headroom and is a practical alternative for the SPX3819M5-3.0.
