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 & 3)

Operating Junction Temperature Range
SG117A/SG117 ......................................... -55°C to 150°C
SG217A/SG217 ......................................... -25°C to 150°C
Note 2. Range over which the device is functional.
SG317A/SG317 ............................................ 0°C to 125°C
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 SG117A/SG117 with -55°C ≤ T ≤ 125°C, SG217A/
A
SG217 with -25°C ≤ TA ≤ 150°C, SG 317A/SG317 with 0°C ≤ TA ≤ 125°C, VIN - VOUT = 5.0V , and for IOUT = 500mA (K, R, and IG), and IOUT = 100mA
(T and L packages). Although power dissipation is internally limited, these specifications are applicable for power dissipations of 2W for the T and L
packages, and 20W for the K, R, and IG packages. IMAX is 1.5A for the K, R, and IG packages and 500mA for the T and L packages. Low duty cycle
pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
