LM1117: Low Temprature charactrristics

keeryong yoon
Prodigy 20 points
Part Number: LM1117

Hi...

I'd like to know the difference of LM1117 and LM1117I.

I had some operation test at the -30 degree C. 

There was a little difference of output voltage deviation and change like as the datasheet.   

If there are no problems in our power circuits, can i use  the LM1117 at the -30 degree C instead of LM1117I .

Also I'd like to know the difference of making process at the factory.

For example, durability, duty cycle, output votage deviation, output voltage change.etc.

Thanks...

bst rgds…

    Hi Keeryong,

    The LM1117 and LM1117I differ in test and characterization.  It is important to note that the LM1117 is not tested or characterized for temperatures below 0 C.  If you choose to go outside of the rated operating condition, you may find performance outside of what is represented in the datasheet.

    Very Respectfully,

    Ryan
