The XR46014 is an 80V constant current regulator that can drive upto 250mA. Users may adjust the regulating current from 10mA to 250mA through an external resistor.
 
A linear type over temperature protection function protects the system by decrease the current linearly when the junction temperature of the chip is higher than 125°C. Multiple XR46014 chips can be connected in parallel to provide higher driving current capability. The device is available in the SOT-223-3L package.

 

  • 3V to 80V operation range
  • 270mV low current sense voltage
  • Linear over temperature protection
  • Can be parallel connected for higher current

  • LED lighting applications
    • Downlight
    • High bay
    • Specialty
    • Architectural

The best way to determine this is to go to maxlinear.com and type the part into the search function. At or near the top of the results you should see something that looks like:
 
 
 

In this example, we looked for XRA1201. Click on part number header or on the link at the bottom of the result.  This brings you to the product page. For example:

 
 
 

Click on Parts & Purchasing, highlighted with the blue arrow above. The screen changes to:

 
 
 

Notice the status column and the “Show obsolete parts” link.  A legend tells you the definition of the different statuses. Click on the “Show obsolete parts” link to see EOL or OBS part numbers along with the Active part numbers, the legend still present:

 
 
 

Another method to find out if a part is OBS or EOL is to click on SUPPORT at the top:

 
 
 

And then Product Change Notifications:

 
  
 

Type the part into the search, and click on one of the part numbers from the drop down menu. Then you can look for the Product Discontinuation Notice, which generally is at the top of the list, for example:

 
 
 

If you see this, it tells you that this particular orderable part has been discontinued and when the last order date is, or was. If you click on the file, then you can view the notice we sent about this if you purchased the part in the recent past. It may also advise of a replacement part. When an orderable part first becomes discontinued, Product Discontinuation Notices are sent are sent to those who have purchased the parts in the recent past, if purchased directly, with a dated opportunity to place a last order.
