(*3) Full range： BU7261, BU7262：Ta=-40[℃] to +85[℃] BU7261S, BU7262S：Ta=-40[℃] to +105[℃]
(*4) Under the high temperature environment, consider the power dissipation of IC when selecting the output current.
When the terminal short circuits are continuously output, the output current is reduced to climb to the temperature inside IC.
