: Capacitor for noise absorption when the motor rotates.
Use the IC with C
M
set to 0.1
μ
F or less.
R
O
: Resistance for current limitation with the output short-
circuited.
Use the IC with R
O
set to 2 to 3 (1 Watt class or higher).
R

: Resistance for setting “H” output voltage.
“H” output voltage V
