use ADP2360 as a current source

hi

i want to use ADP2360 as a current source in my design. so i connected FB pin to a current shunt resistor .

i intend to get 20ma current over temprature range -40 to 85 .

ADP2360 has an internal 0.8v internal reference voltage and i am worry about drift of this voltage .

 

i am worry about drift of current over temperature range of -40 to 85 .i need my current to remain as well constant in this whole range. (0.05ma drift at worst case).

 

in device like ADP2441 there is a TRK pin which you can apply a voltage by a low drift voltage reference but in  ADP2360  there is no such pin.

 

is ADP2360 a right solution for my design?
