The datasheet is not very clear to me.
I am using the minimum ripple circuit configuration with R3, C1, and C2 (Sheet 19).
I have tried to simulate this using the Webench tool, however, the Webench tool does not use this circuit configuration and I don't know any way to modify the circuit configuration to include this network.
I have tried to change the output cap to a ceramic type and the tool does not want me to do that. I get a message that the output cap ESR needs to be between ~ 1.0 ohms to 1.7 ohms or the regulator will be unstable but remember this is without the minimum ripple configuration network.
Is this correct even when using the minimum ripple circuit configuration? I would prefer to use a ceramic output cap but don't not want to add an additional series resistor.
