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 0.01
μ
F to 0.1
μ
F,
between VCC
and REF terminals in order to prevent from irregular
output pulse at start-up.
