Exceeding the absolute maximum ratings may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended.
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 coef?cient is ΔV 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 ≤ 750mA, T J = T MAX .
Note 11. Thermal regulation is de?ned as the change in output voltage at a time t after a change in power dissipation is applied, excluding load or line
regulation effects. Speci?cations are for a 200mA load pulse at V IN = 16V for t = 10ms.
Note 12. Speci?cation for packaged product only.
