Notes:

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 circuit layout. See “Applications Information.”

Specification for packaged product only.

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.

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

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.
