LA317 Datasheet | Taitron Components

Description - The LA317 is an adjustable 3-terminal positive voltage regulator with a very low dropout of 1.2V at 1A output current. Using 2 external resistors, the LA317 can provide an adjustable output voltage down to 1.25V. - The LA317 is available in standard SOT-223, D-PACK, TO-220 and D2-PACK packages.
