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, TO-
39 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.
FEATURES
• Fully compatible with TTL and DTL
• Output current in excess of 1A
• Internal thermal overload protection
• No additional external components
• Bandgap reference voltage
• Foldback current limiting
