Texas Instruments LM3490
The LM3490 is an integrated linear voltage regulator. It features operation from an input as high as 30V and a specified maximum dropout of 1.2V at the full 100 mA load. The 5, 12, and 15V members of the LM3490 series are intended as tiny alternatives to industry standard LM78LXX series and similar devices.| Part No. | LM3490 |

DESCRIPTION
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 1.2V quasi low dropout of LM3490 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. The LM3490 series features a 3.3V member.
