: Input capacitor (Approx. 10
µ
F)
This capacitor is required when the input line contains induc-
tance or when the wiring is long.
C
O
: Output capacitor (47
µ
F or higher)
The output voltage may oscillate if a low ESR type capacitor
(such as a ceramic capacitor) is used for the output capacitor
in SI-3000ZF.
R1, R2: Output voltage setting resistors
The output voltage can be set by connecting R1 and R2 as
shown at left.
The recommended value for R2 is 10kΩ or 11kΩ.
