General Description

The LM3490 is an integrated linear voltage regulator. It 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 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. The SOT packaging and quasi low dropout features of the LM3490 series converge in this device to provide a very nice, very tiny 3.3V, 100 mA bias supply that regulates directly off the system 5V±5% power supply.

Features

3.3, 5, 12, and 15V versions available
Logic-controlled ON/OFF#
Packaged in the tiny 5-lead SOT-23 package

Key Specification

30V maximum input for operation
1.2V guaranteed maximum dropout over full load and temperature ranges
100 mA guaranteed load current
±5% guaranteed output voltage tolerance over full load and temperature ranges
-40 to +125°C junction temperature range for operation

Applications

Tiny alternative to LM78LXX series and similar devices
Tiny 5V±5% to 3.3V, 100 mA converter
Post regulator for switching DC/DC converter
Bias supply for analog circuits
