■Typical Connection Diagram/Block Diagram

■Reference Data

CIN, CB: Input and bias capacitors (Approx. 0.1 to 10

µF)

Required when the input line contains inductance or when the

wiring is long.

CO: Output capacitor (47

µF 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 500m

Ω 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 10k

Ω.

R1= (VO–VADJ) / (VADJ/R2)

CSS: Soft start capacitor

The rising time of the output voltage can be set by connecting

CSS between VOUT and ADJ.
