I think that's the default latex appearance for in-line expression of limit. If you want the upper one, put your limit expression between [tеx] and [/tex],

[tex]\lim_{a\to b}[/tex]

To do the same task, you can also sandwich it within a pair of $$,

$$\lim_{a\to b}$$

If you want it inline, you can use the \displaystyle tag:
$\displaystyle \lim_{a\to b}$
Also works also for integrals and sums.
