Exceeding the absolute maximum rating may damage the device.

The device is not guaranteed to function outside its operating rating.

Devices are ESD sensitive. Handling precautions recommended.

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

Output voltage temperature coefficient is defined as the ∆VOUT(worst case) ÷ (TJ(max) – TJ(min)) where TJ(max) is +125°C and TJ(min) is 0°C.

VDO = VIN – VOUT when VOUT decreases to 99% of its nominal output voltage with VIN = VOUT + 1V.

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

VEN ≤ 0.8V and VIN ≤ 8V, VOUT = 0.
