  • RE: PMP8372: use two TPS7A47/TPS7A33 in parallel?

    Hi Anber, i believe for LDO, the power dissipation is fixed no matter you parallel one more or not in the power flow. For LDO in parallel design guide, could you raise another E2E with this two LDO parts regarding their parallel operation. so an expert…

  • RE: TPS7A3301 TPS7A4700 protection diodes

    Resolved
    Hi JD, Protection diodes should not be required. In fact if you are using TPS7A3301 and TPS7A4700 for their PSRR, such diodes would actually reduce the PSRR. We have a reference design that may be useful to you: http://www.ti.com/tool/pmp8372 Very Respectfully…
