Application Scenarios & Design Considerations

Cap-Free, NMOS, 250mA Low Dropout Regulator with Reverse Current Protection

Alternative Part Number

  • LP2985AIM5-1.8 --: Low-dropout 1.8V linear regulator in SOT-23-5 with similar current capability and low noise, a common drop-in style alternative when the DCQ package is not required.
  • MIC5219-1.8YM5 --: 1.8V LDO regulator in SOT-23-5 with low dropout and good PSRR, suitable replacement for low-power 1.8V rail applications.
  • AP2112K-1.8TRG1 --: 1.8V fixed LDO in SOT-23-5 offering low quiescent current and stable performance, a cost-effective alternative for similar 1.8V regulation needs.
