Notes:
1. Exceeding the absolute maximum ratings 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. Output voltage temperature coefficient is Δ V OUT(worst case) ÷ (T J(max) – T J(min) ) where T J(max) is +125°C and T J(min) is –40°C.
7. V DO = V IN – V OUT when V OUT decreases to 99% of its nominal output voltage with V IN = V OUT + 1V. For output voltages below 2.5V, dropout voltage
is the input-to-output voltage differential with the minimum input voltage being 2.5V. Minimum input operating voltage is 2.5V.
8. I GND is the quiescent current. I IN = I GND + I OUT .
9. V EN ≤ 0.8V, V IN ≤ 8V, and V OUT = 0V
10. For a 1.8V device, V IN = 2.5V.
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 = 8V for t = 10ms.
