DESCRIPTION
The LM3480 is an integrated linear voltage regulator.
It features operation from an input as high as 30V
and a ensured maximum dropout of 1.2V at the full
100 mA load. Standard packaging for the LM3480 is
the 3-lead SOT-23 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-23 packaging and quasi low dropout features of
the LM3480 series converge in this device to provide
a very nice, very tiny 3.3V, 100 mA bias supply that
regulates directly off the system 5V±5% power
supply.
