    Thread Summary
    
                The user inquired about the difference between ADM7150ACPZ-5.0-R2 and ADM7150ACPZ-5.0-R7. The final answer clarified that both parts are identical 5 V, ultra-low noise, high-PSRR LDOs in LFCSP packages, with the only difference being the tape-and-reel quantity: R2 has 250 units per reel, and R7 has 1,500 units per reel.

    Hi,
    

    I'm planning to use ultra-low noise high-PSRR LDO (ADM7150) in my design. 
    

    Following are my basic requirements:
    

      

    • Vin = 6.2 V
      • 

    • Vout = 5 V
      • 

    • Iout = 350 mA
      • 

    

    I'm going with LFCSP package instead of SOIC due to better thermal performance.
    

    Accordingly, I have two part codes:
    

      

    • ADM7150ACPZ-5.0-R7
      • 

    • ADM7150ACPZ-5.0-R2
      • 

    

    What is the difference between the parts ending in R2 and R7? I'm not able to see it in the datasheet.
    

    

    Thanks,
    

    Binayak

      Hi Team,
      

      The difference between ADM7150ACPZ-5.0-R2 and ADM7150ACPZ-5.0-R7 is purely in the packaging and reel quantityBoth are identical devices (5 V fixed-output, ultra-low noise, high-PSRR LDO in LFCSP package). The suffix “R2” and “R7” indicate different tape-and-reel options used for automated assembly.
      

      Suffix Codes
      

        

      • R2 → Tape-and-reel packaging, typically 250 units per reel
        • 

      • R7 → Tape-and-reel packaging, typically 1,500 units per reel
        •
