LM2991QML: Clarification on regulator circuit LM2991

Part Number: LM2991QML

We use the above circuit. We are observing ouput oscillations when interfaced with our ADC. Kindly provide a detailed explanation for the follwing.

  • Implication of using 0.1uF capacitor or any capacitor at the adjust pin. Whether it will lead to oscillations in the output voltage.
  • C3 is a ceramic capacitor. If we use R2 of value 10 ohms or above will it lead to oscillations at the output.
