Troubleshooting linear voltage regulator

I am wondering what would be a potential cause of a linear voltage regulator not putting out any voltage. It is a 5V linear voltage regulator (ZXTR2105F) with up to 60 V input. I have it set up like the recommended circuit with a 1uF capacitor on input and 10uF capacitor on output. My input is 7-8 VDC. I am only getting 2V out and it is getting very hot. I have checked for shorts and I even soldered on a new one and it is doing the same thing. What are some of the causes of a voltage regulator not functioning properly? Thanks.
