(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(1) The input-to-output differential across the regulator should provide for some margin against regulator operation at the maximum dropout
(for a particular current value). This margin is needed to account for tolerances in both the input voltage (lower limit) and the output
voltage (upper limit). The absolute minimum V
IN
for a desired maximum output current can be calculated by the following:
V
IN(min)
= V
OUT(max)
+ V
DO(max at rated current)
