1 / 9 page LM3480 100 mA, SOT-23, Quasi Low-Dropout Linear Voltage Regulator General Description The LM3480 is an integrated linear voltage regulator. It fea- tures operation from an input as high as 30V and a guaran- teed maximum dropout of 1.2V at the full 100 mA load. Stan- dard packaging for the LM3480 is the 3-lead SuperSOT® package. The 5, 12, and 15V members of the LM3480 series are in- tended 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 appli- cations where the 2 to 2.5V dropout of LM78LXX series de- vices precludes their (LM78LXX series devices) use. The LM3480 series features a 3.3V member. The SOT pack- aging 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.
