Default Control Shutdown (enable) pin of LT1963A voltage regulator with Open collector

Hi all,

I am trying to put a simple voltage regulator into stanby-mode using an open collector outbput from an atmega.

I am not sure though that the way I achieved this result is very academic - I have not used any pull-up resistor as stipulated in the regulator datasheet as I could not figure out how exactly to do it.

The sim is attached hereunder.

Could someone with more insight kindly point me on how to implement this correctly ?

Thanks in advance,
