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 T_A⛃T_J, and variations in the parameter of all measurement (except for Temperature
Coefficient of Output Voltage)caused by temperature change are not considered.
