LM3490  
100 mA, SOT-23, Quasi Low-Dropout Linear Voltage  
Regulator with Logic-Controlled ON/OFF  
General Description  
Key Specifications  
The LM3490 is an integrated linear voltage regulator. It fea-  
tures operation from an input as high as 30V and a guaran-  
teed 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 need-  
ed.  
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  
The 5, 12, and 15V members of the LM3490 series are in-  
tended 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 appli-  
cations where the 2 to 2.5V dropout of LM78LXX series  
devices precludes their (LM78LXX series devices) use.  
Features  
3.3, 5, 12, and 15V versions available  
Logic-controlled ON/OFF  
Packaged in the tiny 5-lead SOT-23 package  
The LM3490 series features a 3.3V member. The SOT pack-  
aging 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.  
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
