  • RE: Ripple rejection of TPS79147 and TPS79101

    Hi Martin, It is very difficult to get high PSRR performance with 300mV and 167mV in/out differential. The TPS799 does not look like it will meet your requirements. You may need to increase your input voltage requirement and increase the output cap more…

  • TPS79101 measured output voltage differs from the calculated value

    Hello, I am encountering an issue with TPS79101DBV in a prototype. Referring to the attached image, the measured voltage at node V_3V5 is not 3.5 V but something around 3.33 V. Both regulators have +5 V for input that comes from a USB connection (after…
