Note 1: Absolute Maximum Rating is limits beyond which damage to the device may occur. For guaranteed
specifications and test conditions see the electrical characteristics.
Note 2: Maximum positive supply voltage of 35V must be limited duration (<100mS) and duty cycle (<1%).
Note 3: The maximum allowable power dissipation is a function of the maximum junction temperature, T_J, the junction
to ambient thermal resistance, θ_JA, 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 θ_JA 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 400mA at the
maximum specified temperature.
