*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.

tempera-
ture range. VOUT-LOW = Lowest voltage measured over the temperature range.
4: Load regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is
tested over a load range from 1mA to the maximum specified output current. Changes in output voltage due to heating
effects are determined using thermal regulation specification TCVOUT.
5: Thermal regulation is defined as the change in output voltage at a time t after a change in power dissipation is applied.
Specifications are for a current pulse equal to ILMAX at VIN = 6.0V for t = 10 msec.
6: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value
with a 1V differential applied.
7: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temper-
ature and the thermal resistance from junction to air. (i.e. TA, TJ, θJA). Exceeding the maximum allowable power dissipa-
tion will cause the device operating junction temperature to exceed the maximum 150°C rating. Sustained junction
temperatures above 150°C can impact the device reliability.
8: VTH-MIN = 2.55V and VTH-MAX = 2.70V.
9: 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 Ambi-
ent temperature is not significant.
