FEATURES
DESCRIPTION
The LM3480 is an integrated linear voltage regulator.
2
3.3, 5, 12, and 15V Versions Available
It features operation from an input as high as 30V
Packaged in the Tiny 3-Lead SOT-23 Package
and a ensured maximum dropout of 1.2V at the full
100 mA load. Standard packaging for the LM3480 is
