NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed
circuit board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the
declared operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device
specification limit values are applied individually under normal operating conditions and not valid simultaneously.
4. Guaranteed by design and characterization
5. These values take into account the tolerance of the cms capacitor used. The allowed values are single or distributed capacitor combination
not exceeding 1.2 mF with 100 nF + 220 nF typical and recommended. It is recommended to use X5R or X7Rtype capacitors with very
low ESR (< 100 mW) for optimal performances.
