C1, C2: Use ceramic capacitors (see table below); C3: For best performance, use a 100 μF or more capacitor. 2. C1, C2, & C3 are required and should be placed close to the pins of the converter, with shortest possible leads. 3. R1 is used when trimming down. R2 is used when trimming up. 4. No parallel connection or plug and play.
