TLV700: Application issues.

Tool/software:

Hi team,

Please refer to the attached schematic diagram.

The current issue is that the output voltage of U4 is unstable during operation, causing the U1 MCU to repeatedly restart.

Using an oscilloscope to measure, it was found that the output voltage is 3.3V under normal conditions and 2.5V under abnormal conditions.

Please help analyze the reason, thank you!

    Hello,

    Thank you for your inquiry.

    What do you mean by abnormal conditions?

    Could you please send an oscilloscope shot with the input, output, and load current present in the waveform?

    What is the purpose of D1 in the schematic?

    I am not noticing anything abnormal with the schematic. 

    Best Regards,

    Hannah
