ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SG137A/SG137 with -55°C T
SG237 with -25°C T
= 100mA (T and L packages). Although power dissipation is internally limited, these specifications are applicable for power dissipations of 2 for the T and
L packages, and 20 for the K, R, and IG packages. I
testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
