Junction Temperature Calculation: TJ = TA + (PD x θJA). Note B. The above numbers for θ JC are maximums for the limiting thermal resistance of the package in a standard mounting configuration. The θ JA numbers are meant to be guidelines for the thermal performance of the device/pcboard system. All of the above assume no ambient airflow. RECOMMENDED OPERATING CONDITIONS (Note 2 & 3) Input Voltage Range ................................. (VOUT + 3.5V) to 37V Operating Junction Temperature Range SGR117A ........................................................-55°C to 150°C Note 2. Range over which the device is functional. Note 3. These ratings are applicable for junction temperatures of less than 150°C. ELECTRICAL CHARACTERISTICS (Unless otherwise specified, these specifications apply over full operating ambient temperatures for SGR117 with -55°C ≤ TA ≤ 125°C, VIN - VOUT = 5.0V, and for IOUT = 500mA (K and IG), and IOUT = 100mA (T package). Although power dissipation is internally limited, these specifications are applicable for power dissipations of 2W for the T package, and 20W for the K and IG packages. IMAX is 1.5A for the K and IG packages and 500mA for the T package. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
