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: The device is not guaranteed to operate outside its operating rating.
Note 3: Devices are ESD sensitive. Handling precautions recommended.
Note 4: The maximum allowable power dissipation is a function of the maximum junction temperature, Tj, 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, Pd

Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops -1% below its
nominal value measured at 1V differential.
Note 6: 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, Iin = Ignd + Iout.
