3.2 Output Capacitor

The REF70 requires an output capacitor between 0.1 uF to 100uF for proper operation and stability. Larger capacitors are able to help with load transcient respones.

A large capacitor can also help with lowering the broadband/white noise. It is necessary to understand output capacitors when selecting the capacitor for the appliation.
