Note 1. Stresses listed as the above "Absolute Maximum Ratings" may cause permanent damage to the device. These
Note 2. θ
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 I
Note 6. Standby current is the input current drawn by a regulator when the output voltage is disabled by a shutdown
Note 7. The dropout voltage is defined as V
Note 8. Regulation is measured at constant junction temperature by using a 20ms current pulse. Devices are tested for
Note 9. The EN threshold should be higher than V
