The wavelenghts which have the most detrimental effect are  
reds and infra-reds, which means that the fluorescent light-  
ing used inside most buildings has very little effect on perfor-  
mance. A micro SMD test board was brought to within 1 cm  
of a fluorescent desk lamp and the effect on the regulated  
output voltage was negligible, showing a deviation of less  
than 0.1% from nominal.  
Application Hints (Continued)  
For best results during assembly, alignment ordinals on the  
PC board may be used to facilitate placement of the micro  
SMD device.  
Micro SMD Light Sensitivity  
Exposing the micro SMD device to direct sunlight will cause  
misoperation of the device. Light sources such as Halogen  
lamps can also affect electrical performance if brought near  
to the device.
