Current Limit of LT3045

Hi,

The LT3045 can be configured for customized current limiting by connecting a resistor from ILIM to GND. The output current will be limited to 500*0.3/Rilim, as the ILIM current is 1/500 of the output current and the LT3045 limits the output current so that 0.3V at ILIM is not exceed.

The graphs in the datasheet show the according short cut current that flows out of the output terminal when the output is shorted to GND.

How tight is the clamping to these 0.3V in a current limiting situation?

Like how far from these 0.3V away does the LT3045 start to decrease the output voltage?

Ideally, at an ILIM voltage of 0.2999999999999999999999 volts, the output voltage would still be within +-2mV of the SET terminal, but as the gain of the according amplifier comparing the ILIM voltage and the internal 0.3V reference has to be finite, the output will have to deteriorate from VSET+-2mV also at some point before 0.3V is reached.

Is there some kind of graph that shows this behavior?

Regards,
Gerd
P.S.:
I am aware that the current ratio of 500 has some tolerance, as does the 0.3V internal reference voltage (I assume it is similar to the VGFB Trip Point voltage range of 291 to 309mV, which would make the current ratio range from 468 to 539 in order to arrive at the +-10% tolerance of the programmable current limit as specified in the datasheet).
This question is not about these tolerances, but about the behavior in the vicinity of the actual ILIM "tripping" voltage.
