2. This product is not designed for protection against radioactive rays.
3. All characteristic are measured with a capacity across the input (0.33μF) and the output (22μF).
Measurement is done at TAâTJ, and variations in the parameter of all measurement (except for
Temperature Coefficient of Output Voltage) caused by temperature change are not considered.
