Parts tolerances characteristics are not defined in the circuit design
sample shown above. When designing an actual circuit for a product,
you must determine parts tolerances and characteristics for safe and
economical operation.
Please connect a capacitor, which the value is about 0.01µF to 0.1µF,
between VCC and REF terminals in order to prevent from irregular
output pulse at start up.
