SG109 regulators equivalent, 5 -volt fixed voltage regulators.
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 dissi.
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 featur.
