Application Scenarios & Design Considerations

150mA, High PSRR, Low Quiescent Current, Low Noise LDO 5-SC70 -40 to 125

Alternative Part Number

  • LP5907MFX-2.9/NOPB --: Low-noise 250 mA LDO in SOT-23-5 with fixed 2.9 V output, functionally similar to the TPS71729 and available in a smaller package.
  • ADP151AUJZ-2.9-R7 --: Ultra-low-noise 200 mA CMOS LDO with 2.9 V fixed output, comparable ripple and PSRR performance for sensitive analog rails.
  • MIC5504-2.9YM5-TR --: 300 mA low-dropout regulator with 2.9 V fixed output in SOT-23-5, offering similar current capability and a cost-effective alternative.
