ELECTRICAL CHARACTERISTICS

(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG109 with -55°C

≤ T

0°C

≤ T

125°C, and for V

IN

= 10V, I

OUT

= 500mA (K, R, and IG -Power Packages-) and I

OUT

= 100mA (T-package). Low duty cycle pulse testing techniques

are used which maintains junction and case temperatures equal to the ambient temperature.)
