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?
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?
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?
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…
Please do SYNC RELEASE in LTspice. The model has been released. Thanks!
Why the PSRR and Noise graphed stop at 10MHz? Can I gae the data up to 200MHz?
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?
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?
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…
