(2) although we are confident in recommending the sample applic ation circuits, carefully check their characteristics further when using them. when modifying externally attached comp onent constants before use, det ermine them so that they have sufficient margins by taking into account variations in externally attached components and the rohm lsi, not only for static characteristics but also including transient characteristics. (3) absolute maximum ratings operating or testing the device over the maximum specifications may damage the part itself as well as peripheral components. therefore, please ensur e that the specificatio ns are not exceeded. (4) gnd potential ensure that the gnd terminal is at the lowe st potential under all operating conditions. (5) thermal design use a thermal design that allows for a sufficient margin regar ding power dissipation (pd) under actual operating conditions. (6) terminal shorts and mis-mounting incorrect orientation or misalignment of the ic when mounting to the pcb may damage part. short-circuits caused by the introduction of foreign matter between the output terminals or across the output and power supply or gnd may also result in destruction. (7) operation in a strong magnetic field operation in a strong electromagnet ic field may cause malfunction. (8) reset circuit the power on reset circuit, which initializes internal settings, may malfunction during abrupt power ons. therefore, set the time constant so as to satisfy the power source rise time. thermal derating curve ?msop8 board size: 70 x 70 x 1.6mm material : fr4 glass epoxy board (copper foil area less than 3%) fig.18 0 100 200 300 400 500 0 25 50 75 100 125 ta [ ] pd [mw]
