C1 & C2 are low ESR ceramic capacitors used to minimize noise at the regulator. A tantalum or low ESR electrolytic capacitor may also be used. 2. C1 & C2 are required and should be mounted as close to the regulator pins as possible. C3 is required for optimum performance, use 100 |jF OR more. 3. R1 & R2 are used to adjust the regulator output.
