LM4121: Bode plot and output capacitor

Kaji@PAN

Part Number: LM4121

Hi,

I am examining the circuit using the LM4121 device.
I will attach the circuit diagram I created.
Among them, I would like to ask you some questions.

The Bode diagram is shown in Fig.32 and Fig.33 of the data sheet.
Can you show phase characteristics and gain characteristics with the circuit I created?
There is no WEBENCH for this device.

I am planning to use the attached data products as output capacitors.
Is it possible to use this capacitor?
I care whether the ESR value is correct.

Hi Kaji,

I can test this AC on the bench. I can give you the results by the week of November 11.

Hi Kaji,

Thank you for the information. I have edited out because this is a public forum :).
I am currently waiting for the LM4121 devices to arrive but the bench setup is ready for testing.
