These capacitors are required if the input line contains inductance
or the wiring is long. Especially at low temperatures, tantalum
capacitors are recommended for C

and C

.
: Protection diode
This diode is required for protection against reverse biasing of the
input and output. Sanken EU2Z is recommended.
