Problematic, given what you've told us.

 (30V-3.3V) * 0.1A =3D2.67 W dissipation at worst case input. No way the
LP2951 can handle that.
Best case TI D package is 97C/W so the part would be at 300C pretty quickly=
..

What is your actual load current, and what is the rated power for the
package you want to use?
I would suggest a beefier regulator with heat sink, and a separate LVD to
hold part in reset.
