24V AC/DC input

Hi,

My input is 24V AC/DC and output is 3.3V DC at 80mA (max). I am going to use bridge rectifier with ua78m33. My peak voltage is 24*1.414=34V and power dissipation at the regulator will be (34-3.3)=2.5W and I believe both of them are within the device limitation. Did I miss any other criteria?

Thanks.
