† Notice: Stresses above those listed under “Maximum

Ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of

the device at those or any other conditions above those

indicated in the operational listings of this specification

is not implied. Exposure to maximum rating conditions

for extended periods may affect device reliability.

Note 1:

The minimum VIN must meet two conditions: VIN  2.7V and VIN  VR  VDROPOUT(MAX).

VR is the nominal regulator output voltage. VR = 1.2V, 2.5V, etc.

Dropout voltage is defined as the input-to-output voltage differential at which the output voltage drops 3%

below its nominal value that was measured with an input voltage of VIN =VOUT(MAX) +VDROPOUT(MAX).

The junction temperature is approximated by soaking the device under test at an ambient temperature

equal to the desired junction temperature. The test time is small enough such that the rise in the junction

temperature over the ambient temperature is not significant.
