VREF
: Output capacitor (47 to 100F) : Oscillation prevention capacitor (C1: Approx. 47F, C2: 0.33F) These capacitors are required if the input line is inductive and in the case of long wiring. Tantalum capacitors are recommended 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.
