For guaranteed specifications and test conditions see the electrical characteristics. Note 2: Maximum positive supply voltage of 60V must be limited duration (<100mS) and duty cycle (<1%). Note 3: The maximum allowable power dissipation is a function of the maximum junction temperature, Tj, the junction to ambient thermal resistance, θja, and the ambient temperature, Ta. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. The effective value of θja can be reduced by using a heatsink. Note 3: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differential. Note 4: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the ground pin current and output load current. Note 5: Output current will decrease with increasing temperature, but it will be not dropped below 500mA at the maximum specified temperature. |
