DESCRIPTION
This series of products offers a positive and a negative fixed voltage regulator in one
hermetically sealed, 5 PIN package whose outline is similar to the industry standard
TO-247 package. With heat sinking, they can regulate over 1.5 Amp of output current
per device. Standard voltages are + or - 5V, 12V and 15V. Other voltages are
available upon request. Output voltages are internally trimmed to ±2.0% of nominal
voltage. These devices are ideally suited for Military applications where small size
and high reliability are required.
To order, use the following Omnirel part numbers to determine the required
output voltage of each regulator within one package.
