... Watts +50°C OUT (ambient) and similarly derate linearly to +100°C. When operated with 3.0V input voltages, all devices in the UNR D3 Series are more efficient and can operate to +60°C and +55°C, respectively. At 3.6V , devices operate less efficiently, and maximum full-load ambient IN temperatures are reduced to +45° ...
