NOTE:
2. A 10Ω, ¹/₄W supply decoupling resistor is shown in all application circuits of this device. The resistor serves two purposes. First it provides a
means of decoupling the IC directly at its terminal without introducing additional supply resonance due to parallel connected capacitors. Second,
it also provides protection for the device in event of a sustained short circuit applied directly to the output terminals.
