■Typical Connection Diagram/Block Diagram
CIN: Input capacitor (Approx. 10µF)
SI-3011ZF
This capacitor is required when the input line contains induc-
tance or when the wiring is long.

R3
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.

The recommended value for R2 is 10kΩ or 11kΩ.
R1= (VO–VADJ) / (VADJ/R2)
*: Insert R3 in case of setting VO to VO ≤ 1.8V. The recom-
mended value for R3 is 10kΩ.
