Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. 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.
3. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5kΩ in series with 100pF.
4. The device is not guaranteed to function outside its operating rating.
5. For V_IN range of 1.7V to 2.5V, output current is limited to 30mA.
6. Specification for packaged product only.
