Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. The maximum allowable power dissipation of any T
4. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
5. Specification for packaged product only.
6. Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal V
J
IN
the dropout voltage is the input-to-output differential with the minimum input voltage 2.3V.
power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
