... In this example, the LM1108 dissipates a maximum of 260mW; below the allow able limit of 508 similar manner, Equation 2-1 and Equation 2-2 can be used to calculate maximum current and/or input voltage limits. For example, the maximum allowable VIN, is found by sustituting the maximum allowable power dissipation of 508 mW into Equation 2-1, from which VINMAX = 4.6V. 0702-01 Taejin Technology Co.,Ltd. 4 LM1108F/SF HTC ...
