).
Note B. The above numbers for
θ
are maximums for the limiting
thermal resistance of the package in a standard mount-
ing configuration. The
θ
numbers are meant to be
guidelines for the thermal performance of the device/pc-
board system. All of the above assume no ambient
airflow.

ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SGR117 with -55°C
≤
T
≤
125°C, V
- V
=
5.0V, and for I
= 500mA (K and IG), and I
= 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. I
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.)
