*1 When used at temperatures higher than Ta=25℃, the power is reduced by 5.4mW per 1℃ above 25℃.
*2 When used at temperatures higher than Ta=25℃, the power is reduced by 4.0mW per 1℃ above 25℃.
*3 When used at temperatures higher than Ta=25℃, the power is reduced by 2.1mW per 1℃ above 25℃.
*4 When a ROHM standard circuit board (70mm×70mm×1.6mm, glass epoxy board)is mounted.
