Original question:

LM117HVQML:LM117

LM117HVQML:LM117HVQML

HIROKAZU MONMA
Prodigy 40 points
Part Number: LM117HVQML

Tool/software:

Thank you for contacting us.
Please let me know again.

If the frequency is 1MHz to 400MHz and the output capacitor is 6000μF, is it possible that the PSRR will fall below 10dB?

Also, if it falls below 10dB, how low can it fall?

Thank you in advance.

    Hello Hirokazu-San,

    It is not possible to predict with certainty whether the PSRR will fall below 10dB or how low it will fall for your specific output capacitor value. This is something we will have to test in the lab. I forgot to add in my last answer that for this 3-terminal device, the PSRR is also influenced by CADJ. You would also have to pick a value for CADJ to get a ballpark estimate. The plots in the datasheet are made with COUT = 0 uF.

    Best regards
