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. PD(max) = (TJ(max) – TA) ÷ θJA, where θJA depends upon the printed circuit layout. See “Applications Information.”

5. Specification for packaged product only.

6. Output voltage temperature coefficient is ΔVOUT(worst case) ÷ (TJ(max) – TJ(min)) where TJ(max) is +125°C and TJ(min) is –40°C.

7. VDO = VIN – VOUT when VOUT decreases to 99% of its nominal output voltage with VIN = VOUT + 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. IGND is the quiescent current. IIN = IGND + IOUT.

9. VEN ≤ 0.8V, VIN ≤ 8V, and VOUT = 0V

10. For a 1.8V device, VIN = 2.5V.

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 VIN = 8V for t = 10ms.
