Hi Ryan,
you are correct, the additional question is about LP2985LV-N (LP2985AIM5-1.5). you are right this family does not offer the 3.3V. i think the 3.3V curve i say was in the LP2985 datasheet and not LP2985LV-N.
i will share the information you…
Garry,
The smaller package is for the LP2985LV-N (from our National Semiconductor line of products) only.

Jake,
We do not have fixed 1.5V shunt or series regulators.
We do have 1% LDO that is 1.5V. It can source 1.5V, but it won't sink current. Here is the lowest cost option, LP2985LV-N
