Note: 1. Design Guarantee. (Outgoing inspection is not done on all products.)
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_AÝT_J, and variations in the parameter of all measurement
(except for temperature coefficient of output voltage)caused by temperature change are not considered.
