Product Summary

The LM3490IM5-5.0 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 LM3490IM5X-5.0 is the 5-lead SOT-23 package. A logic-controlled ON/OFF feature makes the LM3490IM5-5.0 ideal for powering subsystems ON and OFF as needed. The applications of the device are (1)Tiny alternative to LM78LXX series and similar devices; (2)Tiny 5V±5% to 3.3V, 100 mA converter; (3)Post regulator for switching DC/DC converter; (4)Bias supply for analog circuits.
