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 TCV
OUT
.
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 I
LMAX
at V
IN
= 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. T
A
, T
J
,
θ
JA
). 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:
V
TH-MIN
= 2.55V and V
TH-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.
