LT3081 SHUTDOWN - APPLIES TO MANY LT308X LDOS

Question

A customer essentially asks, "What is the easiest way to shutdown the LT3081 using a positive referenced logic signal?" I get this question a lot so I will answer myself in a reply post.

The easiest way to shutdown the LT3081 is to disconnect its input - the IN pin. If that is not possible, then I show two other options in the images below. To make the images, I added some commentary to the Adding Shutdown TYPICAL APPLICATION from the LT3085 datasheet, which was the closest reference design that I could find.)
