• Protection diodes with ADP7142

    When we use a linear regulator, I think some diodes are connected to it to protect from reverse voltage and over voltage.


    I'm considering using ADP7142, but no description about these diodes is found on the ADP7142 datasheet.
    Does it mean that these…

  • RE: ADP7118 & ADP7142 Adjustable Formula Error

    Yes, this note refers to the adjustable chip. But not to the chips with fixed outputs. I make an example, in the schematic below the output voltage is 5V (R67 unfitted). You can check if you buy your eval board https://www.analog.com/en/design-center…

  • ADP7142:increasing output current

    I am adding a npn transistor to the output of ADP7142 to increase the current provided at the output while keeping the output voltage as 6V.

    The simulations in LTspice do not seem to be working. Can this scheme be used to increase the current or do I…

  • ADP7142 Spice Model

    Original Question: ADP7142 Spice Model by peter.clerico

    Hello,

    Is a Spice model for the ADP7142 planned, and if so can you indicate when it is expected to be ready?

    Thanks

    Hi Peter,

    Yes, the simulation…

  • ADP7142 - Minimum thermal pad shrink with solder mask

    Hi,

    I am putting .010 wide solder mask between the perimeter pads and the center pads of the manufacturer recommended footprint. The center pad shrinks in size by 36% to accommodate the solder mask width. Is 36% reduction of the center pad a problem thermally…

  • ADP7142(ARDZ-5.0-R7) output out of range, fixed in -0.786v

    Hi all, I hope you can help me with the following:

     

    I'm testing a dual power supply with the adp7142 for +10v (positive 200mA) and the tps7a30 for -10v (negative 200mA). The source is a pair of 12v batteries in series configuration so the adp714…

  • ADP7142 for use with ADAU1701

    I need to drop down from a higher voltage than the venerable ADP3336 can handle and so I'm looking at the ADP7142.  It's only rated for 200ma of current though compared to the 800ma for the 3336 but I think that's still enough for the 1701. …
