Part Number: TPS717

Dear Sirs,

I would like to ask you, whether it is possible (similar as on TPS73101)

to lower output noise of TPS71701 (fixed voltage version) using 1nF capacitor connected to FB pin.

Best regards,

Emil

Hello Emil,

You can use a Cff to help lower the noise. The Cff would be connected from Vout to Vfb as you have suggested. Typical values of Cff are in the range of 100pF to 10nF.

Thanks,
