SG309

SG109/SG309 5 -VOLT FIXED VOLTAGE REGULATORS DESCRIPTION The SG109/SG309 is a completely self-contained 5V regulator. Designed to provide local regualtion at currents up to 1A for digital logic cards, this device is available in the hermetic TO-3, TO-66, TO39 and hermetic and plastic TO-220. A major feature of the SG109's design is its built-in protective features which make it essentially blowout proof. These consist of both current limiting to control the peak currents and thermal shutdown to protect against excessive power dissipation. With the only added component being a possible need for an input bypass capacitor, this regulator becomes extremely easy to apply. Utilizing an improved Bandgap reference design, problems have been eliminated that are normally associated with the zener diode references, such as drift in output voltage and large changes in the line and load regulation.

ELECTRICAL CHARACTERISTICS (Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG109 with -55°C ≤ TA ≤ 150°C, SG309 with 0°C ≤ TA ≤ 125°C, and for V IN = 10V, IOUT = 500mA (K, R, and IG -Power Packages-) and IOUT = 100mA (T-package). Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
