2.0 LM431 micro SMD Light Sensitivity
Application Info
When the LM431 micro SMD package is exposed to bright
sunlight, normal office fluorescent light, and other LED’s and
lasers, it operates within the guaranteed limits specified in
the electrical characteristics table.
1.0 Mounting
To ensure that the geometry of the micro SMD package
maintains good physical contact with the printed circuit
board, pin A1 (NC) must be soldered to the pcb. Please see
AN-1112 for more detailed information regarding board
mounting techniques for the micro SMD package.
