STANDARD APPLICATION CIRCUIT

Note:

1. C1 and C2 are required and should be fitted close to the converter pins.

2. The capacitance of C1,C2 sees external capacitor table, it can be increased properly if required, and tantalum or low ESR electrolytic capacitors may also suffice.

3. No parallel connection or plug and play.
