: Output capacitor (47 to 100µF)

: Oscillation prevention capacitor

(C1: Approx. 47µF, C2: 0.33µF)

These capacitors are required if the input line is inductive

and in the case of long wiring. Tantalum capacitors are rec-

ommended for C1 and C0, particularly at low temperatures.

: Protection diode

This diode is required for protection against reverse biasing

of the input and output. Sanken EU2Z is recommended.
