DESCRIPTION
The 117/317 Series regulators are adjustable 3 terminal voltage regulators capable of supplying in excess of 1.5A over an output
voltage range of 1.25V to 40V (HV Series, 60V). The regulators are exceptionally easy to apply requiring only 2 external resistors
to set the output voltage.
Every effort has been made to make these devices easy to use and difficult to damage. Internal current limiting and power
limiting coupled with true thermal limiting prevents damage due to overloads or shorts, even if the regulators are not fastened
to a heat sink.
