• RE: ADRV9009 FMC board - would using an ultra low noise LDO on the VCXO supply input improve performance?

    You can consider deriving supply for AD9528 and VCXO from ADM7154 LDO. 

    Input to ADM7154 can be from ADP5054.

    Hello

    I want to use ADM7154 LDO in my design.

    could you please share gerber files of ADM7154 LFCSP Eval Board?

    if I want to use it for clock ciruitry in my DAQ system, do you have any recommendations for GND path? I think in the gerber files of AD…

  • Does the output noise of the ADM7154/ADM7155 scale with the output voltage?

    Does the output noise of the ADM7154/ADM7155 scale with the output voltage?

     

    Unlike the majority of low noise LDOs where the output noise increases with the
    output voltage,  the unique architecture of the ADM7154/ADM7155 keeps
    the output…
  • ADM7154, ADM7155: Is the soft start time programmable?

    ADM7154, ADM7155: Is the soft start time programmable?

     

    Yes. ADM7154/ADM7155 use internal soft start to limit the inrush current. The
    rise time in seconds of output voltage (from 10% to 90%) is approximately
    0.0012×Cbyp (Cbyp in uF)
  • RE: similar part to the ADI7150 but lower input voltage

    Hi Belenie,

    Do you mean the similar part to the ultralow noise LDO ADM7150 that takes lower input voltage?

    The ADM7154/5 are the ultralow noise LDOs that take 2.3-5.5V input voltage.

  • RE: LDO for RF LNA

    Hi,

    For RF applications, I suggest you use ADM715x/ADP715x RF LDOs with high PSRR and ultralow noise performance. ADM7154 is a recommended LDO for your application with the following characteristic performance:

    • PSRR:
      • 90 dB (200 Hz to 200 kHz);
      • 58 dB…
  • RE: ADM7154 Dropout voltage

    Hi Alon,

    The dropout voltage does not apply to VOUT voltages less than 2.3V’s.

    At the bottom of the spec table, there is note 3 saying " Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the…

    I'm building test boards for some RFIC's and considering ADM7154-04 as a power supply for 1.2V and 3.3V rails.

    But, since these are test boards, I have to test IC's with power supply which varies +- 5%.
