: Output capacitor (47
µ
F or larger)
SI-3010LLSL is designed to use a low ESR capacitor (such as
a ceramic capacitor) for the output capacitor. The recom-
mended ESR value for an output capacitor is 500mΩ or less
(at room temperature).
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.
