Dear TI experts,
My customer made their schematic with TLV9002QDGKRQ1.
Could you review this schematic?
Best regards,
Chase
Dear Chuck,
Thank you for your support.
Could you review the schematic below?
Best regards,
Chase
Sorry Chase for the delay and thanks for following up.
The TLV9002 cannot drive a 1nF load and be stable. As a general rule of thumb, to allow for changes in Process and Temperature, we recommend a target phase margin of approximately 45 degrees. For the TLV900x family, this would limit cap loads to 200pF. In order to maintain stability with a 1nF load, you would need to add series resistance. So if 1nF is not required, plan on reducing this to something closer to 200pF.

Dear Chuck,
Thank you for your support.
Could you check the schematic below is okay?
Customer added 10Kohm series resistor instead of changing the value of capacitor to set time constant to 10us.

Hi Chase.
What is this application and what is the desired function for this op amp? Could you please describe what the ports on the schematic are?
This configuration is stable as shown here:
