† Notice:

Stresses above those listed under “Absolute 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 intended. Exposure to maximum rating conditions for

extended periods may affect device reliability.

VIN = VIN(min.) to 5.5V

IOUT =50mA (Note 1)

Note 1:

The minimum VIN must meet two conditions: VIN  VIN(MIN) and VIN  VR  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 short enough such that the rise in junction

temperature over the ambient temperature is not significant.

VR is the nominal regulator output voltage. VR = 1.2V, 1.8V, 2.5V, 3.0V, 3.3V or 4.2V.

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).
