Original question:

LP2951: Device marking

LP2951: LP2951MCX

Part Number: LP2951

Hi

Did the LP2951MCXis an active part?  at the web site - the latest datasheet does't include this part.

Did the part name change? if Yes  please send a PCN document

Why the simultor does't support the LP2951MCX part?

    Hi Doron,

    LP2951MCX is not an active part number; however, LP2951CMX is still available from the LP2951-N family.  When TI acquired National Semiconductor, there were some devices that had common family names between the two companies such as LP2951.  While the Orderable Device number did not change, the former National Semiconductor family name was changed to LP2951-N in order to keep the orderable devices associated with the proper datasheet and other technical documentation.

    Very Respectfully,

    Ryan

    Hi Doron,

    All of the LP2951-N devices can be used with an adjustable output or a fixed output based on how the FEEDBACK, SENSE, and VTAP pins are used.  

    The part numbers you list are able to be used either for a 5 V output or adjustable output.

    Very Respectfully,

    Ryan
