SG109 Datasheet 5 -volt Fixed Voltage Regulators

Manufacturer: Microsemi (now Microchip Technology)

Overview: SG109/SG309 5 -VOLT FIXED VOLTAGE REGULATORS.

General 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.

Key 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 i.
