LM3480 Datasheet | National Semiconductor

Description The LM3480 is an integrated linear voltage regulator. It features operation from an input as high as 30V and a guaranteed maximum dropout of 1.2V at the full 100 m A load. Standard packaging for the LM3480 is the 3-lead Super SOT ® package. The 5, 12, and 15V members of the LM3480 series are intended as tiny alternatives to industry standard LM78LXX series and similar devices. The 1.2V quasi low dropout of LM3480 series devices makes them a nice fit in many applications where the 2 to 2.5V dropout of LM78LXX series devices precludes their (LM78LXX series devices) use. The LM3480 series features a 3.3V member. The SOT packaging and quasi low dropout features of the LM3480 series converge in this device to provide a very nice, very tiny 3.3V, 100 m A bias supply that regulates directly off the system 5V ± 5% power supply.
