CR

: Capacitor for noise absorption when the motor rotates.

Use the IC with CM set to 0.1µF or less.

: Resistance for current limitation with the output short-

circuited.

Use the IC with RO set to 2 to 3 (1 Watt class or higher).

: Resistance for setting “H” output voltage.

“H” output voltage VO(H) is given by the following formula:

VO(H) =

VCC1

x

R2

R1+R2

As the resistance values of R1 and R2 are larger,VO(H) for

the output current of VR is higher than the set value.

: When another power supply is used for VR voltage,output

voltage may be oscillated. When this is the case, connect

capacitor CR (approx. 0.01µF) to a portion between VR

and VCC2.
