• 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)

  • ADM7154, ADM7155: What is the recommended headroom voltage?

    ADM7154, ADM7155: What is the recommended headroom voltage?

     

    The recommended headroom voltage (headroom = VIN – VOUT) will depend on the
    requirements in each individual application. These LDOs are typically operated
    at 500mV to 1V  of headroom…

  • ADM7154, ADM7155: Are there any other design considerations for low noise?

    ADM7154, ADM7155: Are there any other design considerations for low noise?

     

    The ADM7154/ADM7155 architecture means that the output noise does not scale
    with voltage for the fixed output voltage models. A simple RC network can be
    added between…

  • 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 noise…

  • ADM7154 PSRR and Noise graphes

    Hello.

    Why the PSRR and Noise graphed stop at 10MHz? Can I gae the data up to 200MHz?

    Thanks

  • ADM7154 EN pin

    If the EN pin is driven to 2.5V while VIN floats, does any damage occur to the part;  Is there any chance there would be backflow current from EN to VIN?

  • ADM7154 enable pin voltage level

    Hi,

    In ADm7154 datasheet, the EN input, Logic HIGH is specified from 1.13 to 1.31V.
    We intend to pull up this pin to voltage input, 5V5.
    Is this correct?

    Regards,
    Vishnu R.

  • [ADM7154] doubt on thermal resistance for SOIC package

    Hi to all,

    on ADM7154 datasheet it's reported thermal resistance for SOIC-8 package (junction-to-ambient) as 36,9 °C/W "in worst case".
    What does "worst case" exactly mean?
    Reading datasheet (Thermal data) I understand thermal…
