XRP6272

2A 5V Adjustable Low Dropout Voltage Regulator
Data Sheet

Description

The XRP6272 is a low dropout voltage regulator capable of a constant output current up to 2 Amps. A wide 1.8V to 6V input voltage range allows for single supply operations from industry standard 1.8V, 2.8V, 3.3V and 5V power rails as well as the 5.8V rail. 

With better than ±2% output voltage accuracy, low output noise and high Power Supply Rejection Ratio (PSRR), the XRP6272 is perfectly suited for powering RF circuits. Optimized for use with small, low cost ESR ceramic output capacitors and featuring a low 30μA quiescent current, this device is also adequate for use in battery powered portable equipment. The XRP6272 operates by default as a 5V fixed output voltage regulator while usage of an external resistor voltage divider allows adjustable output voltages as low as 0.7V. An enable function, power good flag and output noise reduction pin complete the feature set.

Built-in current limit and thermal protections ensure safe operation under abnormal operating conditions.

The XRP6272 is offered in RoHS compliant, green/halogen free 5-pin TO-252 and 8-pin exposed pad SOIC packages.

The best way to determine this is to go to exar.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. When you hover over it, it will turn grey and you can click anywhere in the grey box. This brings you to the product page. For example:

 
 

Click on Parts & Purchasing, highlighted in yellow 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:

 
 

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

 

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.
