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. P_D(MAX) = (T_J(MAX) – T_A) / θ_JA, where θ_JA, depends upon the printed circuit layout. See “Applications Information.”
5. Specification for packaged product only.
6. V_DO = V_IN – V_OUT when V_OUT decreased to 98% of its nominal output voltage with V_IN = V_OUT +1V. For output voltages below 1.75V, dropout voltage
specification does not apply due to a minimum input operating voltage of 2.25V.
7. I_GND is the quiescent current. I_IN = I_GND + I_OUT.
8. Thermal regulation is defined as the change in output voltage at a time t after a change in power dissipation is applied, excluding load or line
regulation effects. Specifications are for a 200mA load pulse at V_IN = 6V for t = 10ms.
