The devices are fully compatible with CECC00802 to 280C which allows them to be placed and reflowed with IC's, thus reducing time and cost in production. The co-planarity of the pin positions is based upon IEC 191-6:1990. The devices are suitable for all applications where high volume production is envisaged.

See derating curve. 12V input types have typically 3% less load regulation change. Supply voltage must be discontinued at the end of the short circuit duration. If components are required in tape and reel format suffix order code with -R, e.g. NTE0505M-R All specifications typical at TA =25C, nominal input voltage and rated output current unless otherwise specified.
