Wondering what happens if the Rtt value is lower than the recommended value.
I have this setup:
Vin: 12V
Vout 1.2V
Cout: 188 uF Ceramic and 220 uF polymer tantalum
I calculate that the Rtt should be at least 3 kOhms.
However, the value used in the design currently is 1.02 kOhms. It seems from section 7.3.7 that the function of this is to optimize the transient response. Apart from sub-optimal transient response what are other effects that may happen with a value this low?
Thanks,
Jon
