Default LT1964-adj Help Needed or Part Needed

Hi, I made a regulator PCB for LT1964 negative voltage regulator with a resistor to adjust the voltage.

Now looking on digikey and the LT datasheet (www.linear.com), I am very confused to see the parts they have do not appear to be the adjustable versions, they appear to be the fixed -5V versions.

So I looked around here and I've got a part-

LT1964ES5-BYP-ND Which, looking at all the data I suspect is -5V too. But I'm not really sure its really hard to figure out!

Anyone know what part this is or if its fixed does anyone have a adjustable version that they can sell me?

-thanks

I think this is pretty clear:

PACKAGE/ORDER INFORMATION
LT1964ES5-SD Adjustable with shut down
LT1964ES5-BYP Adjustable with bypassed voltage reference
LT1964ES5-5 Fixed voltage with both shut down and bypassed voltage reference

Page 2 in big letters, can't miss it.

I checked also with Digikey. They have it very clear stated also. Just type LT1964 and hit SEARCH.
