SG109T-883B

The SG109T/883B is a self-contained 5V regulator designed to provide local regulation at currents up to 1A for digital logic cards. This device is available in the hermetic TO-3 and TO-39 packages. The SG109's design has protective features principally current limiting to control the peak currents and thermal shutdown to protect against excessive power dissipation. These features make the device blowout proof. With the only added component being an optional input bypass capacitor, this regulator becomes extremely easy to apply. Utilizing an improved Bandgap reference design, problems that are normally associated with the Zener diode references, such as, drift in output voltage and large changes in the line and load regulation have been eliminated.
