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.
2. The device is not guaranteed to operate outside its operating rating.
3. Devices are ESD sensitive. Handling precautions recommended.
4. The maximum allowable power dissipation is a function of the maximum junction temperature, TJ, the junction to
ambient thermal resistance, Ó¨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 ӨJA can be reduced by using a heat sink, Pd(max) = (TJ(max) – Ta) / ӨJA.
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.
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.
7. VREF ≤ VOUT ≤ (VIN – 1V), 2.25V ≤ VIN ≤ 16V, 10mA ≤ IL ≤ 1.0A.
8. Output voltage temperature coefficient is ΔVOUT (worse cast) / (TJ(max) – TJ(MIN)) where is TJ(max) +125oC and TJ(MIN) is
0oC.
