  • Forum Post: TPS758A01 is not working

    Hari5670
    Hello All, I'm facing an issue in getting TPS758A01LDO regulator to work, which i have implemented as per the below circuit from data sheet. R1 = 39K, R2=27K. Co = 100uF (electrolytic). Vi = 5V. Expected Vout = 1.25 (1 + (39/27)) = 3V. (approx). The thermal pad id connected the GND. When...

  • Forum Post: TPS51200- Sharing between DDR3 controller

    Praveen Jose
    Hi Techies, I am using an SOIC with two DDR3 controllers inside for a mobile base station application. The configuration for each controller is 32 Bit+4 Bit ECC (128MB - 4 devices for data and One for ECC). So there will be total of 10 on board DDR3 ICs. I have choose TPS51200 for the VTT regulator and...

    Thanks for a reply. But my problem is i am very comfortable with linear regulator's(i don't have any experience with inductor). Actually my input voltage is varied from 10v to 42v.If i use this two regulators LM317KC(TO-220) & UA7805(TO-220)(even efficiency is low ) can i get the...

    Hi all, I am planning to use TPS51206 to generate .75V termination supply for two sets of DDR3 chips on my board. Each set belongs to a different IC. I notice the TPS51206 has a 2A limit. How do I calculate the maximum current my DDR3 chips will draw? Thanks, Titus
