LM4040: Output variation

Hirotsugu Kobayashi

Part Number: LM4040

Hi, team.

Some of the outputs of LM4040AIM3-1.2 are not stable.
It decreases occasionally about 10 mV.
There is no change in input voltage and output current.
Is this normal behavior?

Hi Hirotsugu
This is not normal behavior. LM4040 should give stable o/p for all loads.
Can you specify the load conditions in detail?

Hi Hirotsugu,

this can be the result of overheating during the soldering.
