Hi Katelyn

I am interesting about the last question about output ESR and output capacitance.

Would you provide your suggestion?

Thank you

Amos.

Hello Amos,

You should be entering in the ESR at the switching frequency. If you are using ceramic capacitors, entering 3mR for ESR is fine as a general rule.

hope this helps?
