MICRO SMD LIGHT SENSITIVITY

Exposing the micro SMD device to direct sunlight may cause

mis-operation of the device. Light sources such as Halogen

lamps can effect electrical performance if brought near to the

device.

Light with wavelengths in the red and infra-red part of the

spectrum have the most detrimental effect thus the fluores-

cent lighting used inside most buildings has very little effect

on the output voltage of the device. Tests carried out on a

micro SMD test board showed a negligible effect on the

regulated output voltage when brought within 1cm of a fluo-

rescent lamp. A deviation of less than 0.1% from nominal

output voltage was observed.
