Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These
are for stress ratings. Functional operation of the device at these or any other conditions beyond those indicated
in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions
for extended periods may remain possibility to affect device reliability.
Note 2. θJA is measured in the natural convection at TA = 25°C on a high effective four-layer thermal conductivity test board
of JEDEC 51-7 thermal measurement standard. The measurement case position of θJC is on the expose pad of
the package.
Note 3. Devices are ESD sensitive. Handling precaution is recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
Note 5. Quiescent, or ground current, is the difference between input and output currents. It is defined by IQ = IIN − IOUT
under no load condition (IOUT = 0mA). The total current drawn from the supply is the sum of the load current plus
the ground pin current.
Note 6. Regulation is measured at constant junction temperature by using a 20ms current pulse. Devices are tested for
load regulation in the load range from 1mA to 600mA respectively.
