2 The output ripple voltage may vary depending on the capacitance, environment, and location of peripheral components. Especially right
attention has to be paid to aluminum electrolytic capacitor, because ESR changes greatly at the time of the low temperature and output ripple
voltages increase.

Power Module Usage Precautions : Safety Precautions / 1)The products are designed and manufactured for use in ordinary electronic equipment (i.e. AV/OA/ telecommunication/amusement equipment, home appliances). Please consult with the Company‘s (ROHM) sales staff if intended for use in devices requiring high reliability (e.g. medical/transport/ aircraft/spacecraft equipment, nuclear power/fuel controllers, automotive/safety devices) and whose malfunction may result in injury or death. In this case, failsafe measures must be taken, including the following: [a] installation of protection circuits in order to improve system safety [b] incorporation of redundant circuits in the case of single-circuit failure 2) The products are designed for use under normal conditions. Application in special environments can cause a deterioration in product performance. Therefore, verification and confirmation of product performance, prior to use, is recommended.The following environments are considered to be 'special‘: [a] Outdoors, exposed to direct sunlight or dust [b] in contact with liquids. such as water, oils, chemicals, or organic solvents [c] in areas where exposure to the sea air or corrosive gases (i.e. Ciz. H25, NHa, 802, N02) can occur [d] in places where the products may be in contact with static electricity or electromagnetic waves [e] in proximity to heat-producing items, plastic cords, or flammable materials [f] in contact with sealing or coating products, such as resin [g] in contact with unclean solder or exposed to water or water-soluble cleaning agents used after soldering [h] in areas where dew condensation occurs 3) The products are not designed to be radiation resistant 4) The Company is not responsible for any problems resulting from use of the products under conditions not recommended herein. 5) The Company should be notified of any product safety issues. Moreover, product safety issues should be periodically monitored by the customer. A at on Notes 1) A sufficient margin must be allowed if changes are made to the peripheral circuit due to variations in the inherent tolerances of the external components as well as transient and static characteristics. In addition, please be aware that the Company has not conducted investigations on whether or not particular changes in the example application circuits would result in patent infringement. 2) The application examples, their constants, and other types of information contained herein are applicable only when the products are used in accordance with standard methods. Therefore, if mass production is intended, sufficient consideration to external conditions must be made.
