Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a
load range from 1.0mA to the maximum specified output current. Changes in output voltage due to heating effects are covered
by the thermal regulation specification.
Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value at a 1V
differential.
Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, exclud-
ing load or line regulation effects. Specifications are for a current pulse equal to I
MAX
at V
IN
= 6V for T = 10msec.
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature
and the thermal resistance from junction-to-air (i.e. T
A
, T
J
,
θ
JA
).
Hysteresis voltage is referenced by V
R
.
Time required for V
OUT
to reach 95% of V
R
(output voltage setting), after V
SHDN
is switched from 0 to V
