Notes:
1. 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 µF OR more.
3. R1 & R2 are used to adjust the regulator output. For sug-
gested values, please contact the factory.
