FEATURES  
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.

•
3.3, 5, 12, and 15V Versions Available  
Packaged in the Tiny 3-Lead SOT-23 Package  
APPLICATIONS  
•
Tiny Alternative to LM78LXX Series and  
Similar Devices  
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.

Tiny 5V±5% to 3.3V, 100 mA Converter  
Post Regulator for Switching DC/DC Converter  
Bias Supply for Analog Circuits  
KEY SPECIFICATIONS  
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.
