FEATURES
DESCRIPTION
The LM3490 is an integrated linear voltage regulator.
2
3.3, 5, 12, and 15V Versions Available
It features operation from an input as high as 30V
Logic-Controlled ON/OFF
and a specified maximum dropout of 1.2V at the full
Packaged in the Tiny 5-Lead SOT-23 Package
100 mA load. Standard packaging for the LM3490 is
the
5-lead
SOT-23
package.
A
