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. Devices are ESD sensitive. Handling precaution recommended.

Note 3. The device is not guaranteed to function outside its operating conditions

Note 4. 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 300mA.

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. Standby current is the input current drawn by a regulator when the output voltage is disabled by a shutdown signal

(VEN

2V). It is measured with VIN = 5.5V.

Note 7.

θJA is measured in the natural convection at TA= 25°C on a low effective thermal conductivity test board of

JEDEC

51-3 thermal measurement standard.
