Description	Quasi Low-Dropout Linear Voltage Regulator
Datasheet	LM3-490.pdf
Note	This datasheet PDF includes multiple part numbers: LM3490, LM3. Please refer to the document for exact specifications by model.

The LM3490 is an integrated linear voltage regulator.

operation from an input as high as 30V and a guaranteed maximum dropout of 1.2V at the full 100 mA load. Standard packaging for the LM3490 is the 5-lead SOT-23 package. A logic-controlled ON/OFF feature makes the LM3490 ideal for powering subsystems ON and OFF as needed. The 5, 12, and 15V members of the LM3490 series are intended as tiny alternatives to industry standard LM78LXX series and similar devices. The 1.2V quasi low dropout of LM3490 series devices makes them a nice fit in many applica.
