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

5. Specification for packaged product only.

6. VDO = VIN – VOUT when VOUT decreased to 98% of its nominal output voltage with VIN = VOUT +1V. For output voltages below 1.75V, dropout voltage

speciﬁcation does not apply due to a minimum input operating voltage of 2.25V.

7. IIN is the quiescent current. IIN = IIN + IOUT.

8. For a 2.5V device, VIN = 2.250V (device is in dropout).

9. VREF ≤ VOUT ≤ (VIN –1.0V), 2.25V ≤ VIN ≤ 6.0V, 10mA ≤ IL ≤ 1.5A, TJ = TMAX.

10. 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 = 6V for t = 10ms.
