LM3480 Linear Voltage Regulators

Texas Instruments' 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.
