APPLICATION CIRCUIT

Note: See also Table 1.

Notes:

1. C1 is a ceramic capacitor used to filter high frequency noise.

2. C2 is electrolytic and is recommended to be high frequency and low resistance. For capacitance and current of the capacitor, refer to the datasheet provided by the

manufacturer. Capacitance withstand voltage derating should be 80% or above.
