XB3480M3-5.0

The XB3480M3-3.3/XB3480M3-5.0 is an integrated linear voltage regulator. It features operation from an input as high as 25 V and an ensured maximum dropout of 1.2 V at the full 100 - mA load. Standard packaging for the XB3480M3-3.3/XB3480M3-5.0 is the 3-lead SOT23-3 package. The 5-V members of the XB3480 series are intended as tiny alternatives to industry standard LM78Lxx series and similar devices. The 1.2-V quasi-low dropout of XB3480 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 XB3480 series features a 3.3-V and 5-V member. The SOT23-3 packaging and quasi-low dropout features of the XB3480 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.
