Exceeding the absolute maximum rating may damage the device.
The maximum allowable power dissipation of any T A (ambient temperature) is P D(max) = (T J(max) – T A ) / θ JA . Exceeding the maximum allowable power
dissipation will result in excessive die temperature and the regulator will go into thermal shutdown.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k ? in series with 100pF.
The device is not guaranteed to function outside its operating rating.
For V IN range of 1.7V to 2.5V, output current is limited to 30mA.
Specification for packaged product only.
