NOTES:

1. All voltage values are with respect to the network ground terminal.

2. For operation above 25

°C free-air temperature, derate linearly at the rate of 16.6 mW/°C.

3. For operation above 25

°C case temperature, derate linearly at the rate of 71.4 mW/°C. Due to variations in individual device electrical

characteristics and thermal resistance, the built-in thermal overload protection may be activated at power levels slightly above or

below the rated dissipation.
