Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. Devices are ESD sensitive. Handling precautions recommended.
4. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the loadrange from
0.1mA to 150mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification.
5. Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of the load current plus the groundpin
current.
6. The power good is a function of the output voltage being 5% low and the detection of one of the following: overcurrent, over-temperature ordropout.
