The SP317 is an adjustable three-terminal positive voltage regulator with a very low dropout of 1.2V at 1A output
current. Using 2 external resistors, the SP317 can provide an adjustable output voltage down to 1.25V.
The SP317 includes a circuit of trimmed bandgap reference to assure output voltage accuracy to be within 1%. It
also provides current limiting and thermal shutdown. The current limit is trimmed to ensure specified output current
and controlled short-circuit current. The On-chip thermal limiting provides protection against any combination of
overload and ambient temperature that would create excessive junction temperature.
The SP317 is available in the standard SOT-223, TO-220, TO-252 and TO-263 power packages.
