TPS737: TPS73733

Vibhu Vanjari
Genius 11900 points
Part Number: TPS737

Hello,

I believe the TPS73733 is the 3.3-V fixed voltage version of the LDO. The datasheet says "Fixed voltage versions only—connecting an external capacitor to this pin bypasses noise generated by the internal bandgap, reducing output noise to very low levels." for the Pin Function of NR/FB.

  1. Is there a recommended external capacitor value?
  2. How does an external capacitor on this pin impact output noise, vs an external capacitor on OUT pin?

Thanks,

Vibhu
