LP5907: Please identify the DSBGA package

Chase Jeong

Part Number: LP5907

Hello TI experts,

I have a problem with identifying the package of LP5907.

i need DSBGA package, and i can find 3 different DSBGA drawings in datasheet.

page 31 : 0.64 * 0.64 * 0.33mm (height)

page 37 : 0.64 * 0.64 * 0.495mm

page 40 : 0.64 * 0.64 * 0.445mm

and i cannot find any information how to identify these 3 different package with part number.

i need 2.8V output with DSBGA package. can you give me 3 part numbers based on 3 different heights?

Best regards,

Chase

    Hi Chase,

    Yes LP5907 has 3 different DSBGA packages which varies the height/thickness of the package. Below I've underlined the package designator which can be matched with the mechanical drawings near the end of the datasheet. Note that this devices was originally released by National Semiconductor (NSC) which was then acquired by TI back in 2011 and NSC used a different naming convention which is why the convention has changed over time. 

    LP5907A28YKMR: Height is 0.495mm

    LP5907YKGR-2.8: Height is 0.33mm

    LP5907UVE-2.8/NOPB: Height is 0.44mm  (the old NSC package designator UVE is known at TI as YKE in the mechanical drawing section)

    Dear Kyle,

    Thank you for your reply.

    in fact my customer gave me the part number from their end customer.

    could you identify the part number below?

    LP5907UVX-2.8/NOPB

    which drawing should i see for this part number?

    Best regards,

    Chase

    Hi Chase, 

    The UVX package designator uses the same YKE Mechanical Drawing as the UVE. 

    UVE specifies 250 units on a reel and UVX specifies 3000 units on a reel.

    Hi Kyle,

    i understand clearly, and just one more question.

    the difference among the packages is only the height. rest of the specifications are all the same including electric spec. right?

    Thank you in advance.

    Best regards,

    Chase

    Hi Chase,

    The electrical specs are all the same, the package X & Y dimensions are the same, and the land pattern is the same so they can be used interchangeably as long as you have enough height available in your application.
