    Voltage Regulator not working

    No... I guess I am just wondering what the effect change C7 value had on the output of the regulator. From reading the data sheet it said that a cap larger than 10uF was better to achieve low output ripple, but I am not sure. Also since this is my first pcb I was wondering if there are any...

    Voltage Regulator not working

    Hi, I have just gotten my first pcb printed and back to me to start testing. I am having trouble figuring out what why my voltage regulator isn't working, it should be outputing 5V. I am using the LT3663 http://www.linear.com/product/LT3663 I have attached my schematic. One change is that the C7...

    Lattice Diamond Software

    Hi, I have recently purchased a LatticeECP3 Versa Dev Kit and downloaded Lattice's Diamond Software. I have only used Xilinx in the past and I am wondering how I make test benches in Diamond and then look at the waveform is something like the ISim in Xilinx. Thanks.

    diode polarity

    Hi, I am using a surface mount diode on a pcb I am designing. I have created the footprint in Altium but I can't figure out which pad is the cathode and anode. Which one is the larger pad? Here is the datasheet and the digikey link: http://www.diodes.com/datasheets/ds30516.pdf...

    Altium help. Is the STM32F101 in the Altium libraries?

    Hi, I am new to Altium and PCB design. I am creating a PCB with a micro-controller. I have chosen the STM32F101 for its small size and functionality. I am in the schematic view and I am wondering if Altium has a library with this micro-controller so I can place it on my schematic or if it is not...
