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. Human body model, 1.5kΩ in series with 100pF.
4. Specification for packaged product only
5. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature change.
6. Dropout voltage is defined as the input-to-output differential when output voltage drops to 99% of its normal value with VOUT + 1V applied to VIN.
7. VIN =VOUT (nominal) + 1V. For example, use VIN = 4.3V for a 3.3V regulator or use 6V for a 5V regulator. Employ pulse testing procedure for current limit.
