Note B. The above numbers for θJC are maximums for the limiting
thermal resistance of the package in a standard mount-
ing configuration. The θJA numbers are meant to be
guidelines for the thermal performance of the device/pc-
board system. All of the above assume no ambient
airflow.
RECOMMENDED OPERATING CONDITIONS (Note 2)
Input Voltage .......................................................... 4.5V to 40V
Note 2. Range over which the device is functional.
Operating Ambient Temperature Range
SG1503 ............................................................ -55°C to 125°C
SG2503 ............................................................. -25°C to 85°C
SG3503 ................................................................ 0°C to 70°C
