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.
