TLV751: TLV751application issue

Part Number: TLV751

Hello team,

I would like to ask a question about TLV75101PDSQR. As shown in the picture below, I connected both OUT1 and OUT2 channels of TLV751 to output "FPGA_HSSTAVCCPLL_1.2V" at the same time. What I want to ask is whether I can use OUT1 as shown in the schematic diagram below. Can the two channels of OUT2 be combined into one channel?

    Hi Zoe,

    Thanks for reaching out. What are you trying to achieve by tying OUT1 and OUT2 together? Are you trying to increase the output current? If so, this setup unfortunately won't work, as you'll need to add ballast resistors to ensure one channel does not become dominant. We do have an application note that details how to design for current sharing. That can be found HERE.

    Let me know if this is not the case and you're trying to achieve something else by tying OUT1 and OUT2 together.

    Regards,

    Kelsey
