Note 1. Exceeding the absolute maximum ratings may damage the device.
Note 2. The device is not guaranteed to function outside its operating rating.
Note 3. Devices are ESD sensitive. Handling precautions recommended.
Note 4.

Note 6.
P_D(max) = (T_J(max) – T_A) ÷ θ_JA, where θ_JA depends upon the printed circuit layout. See “Applications Information.”
Output voltage temperature coefficient is ∆V_{OUT(worst case)} ÷ (T_J(max) – T_J(min)) where T_J(max) is +125°C and T_J(min) is –40°C.
V_DO = V_IN – V_OUT when V_OUT decreases to 98% of its nominal output voltage with V_IN = V_OUT + 1V. For output voltages below 2.25V, dropout
voltage is the input-to-output voltage differential with the minimum input voltage being 2.25V. Minimum input operating voltage is 2.25V.
Note 7. I_GND is the quiescent current. I_IN = I_GND + I_OUT.
Note 8. V_EN ≤ 0.8V, V_IN ≤ 8V, and V_OUT = 0V.
Note 9. For a 2.5V device, V_IN = 2.250V (device is in dropout).
Note 10. V_REF ≤ V_OUT ≤ (V_IN – 1V), 2.25V ≤ V_IN ≤ 16V, 10mA ≤ I_L ≤ 1A, T_J = T_MAX.
Note 11. 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 = 16V for t = 10ms.
