LM3490 - Quasi Low-Dropout Linear Voltage Regulator

Download the LM3490 datasheet PDF. This datasheet also covers the LM3 variant, as both devices belong to the same quasi low-dropout linear voltage regulator family and are provided as variant models within a single manufacturer datasheet.

Description

The LM3490 is an integrated linear voltage regulator.

Features

  • 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.
