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, ӨJA, 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 ӨJA can be reduced by using a heat sink, Pd(max) = (TJ(max) – Ta) / ӨJA.

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, IGND = IIN - IOUT for fix output voltage, , IGND = IIN - IOUT

+10mA for fix reference output voltage in full load regulation.

Note 8: Output voltage temperature coefficient is ∆VOUT (worse cast) / (TJ(max) – TJ(MIN)) where is TJ(max) +125

oC and

TJ(MIN) is 0

oC.
