3 Description
The LM3480 is an integrated linear voltage regulator.
It features operation from an input as high as 30 V
and an ensured maximum dropout of 1.2 V at the full
100-mA load. Standard packaging for the LM3480 is
the 3-lead SOT-23 package.
The 5-V, 12-V, and 15-V members of the LM3480
series are intended as tiny alternatives to industry
standard LM78Lxx series and similar devices. The
1.2-V quasi-low dropout of LM3480 series devices
makes them a nice fit in many applications where the
2-V to 2.5-V dropout of LM78Lxx series devices
precludes their (LM78Lxx series devices) use.
The LM3480 series also features a 3.3-V 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, 3.3-V, 100-mA bias
supply that regulates directly off the system 5-V ±5%
power supply.
