The minimum V
IN
has to meet two conditions: V
IN
= 2.7V and V
IN
= V
R
+ V
DROPOUT
.
V
R
is the regulator output voltage setting. For example: V
R
= 1.8V, 2.7V, 2.8V, 2.85V, 3.0V, 3.3V.

Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested
over a load range from 1.0 mA 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 V differential.
Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied,
excluding load or line regulation effects. Specifications are for a current pulse equal to I
MAX
at V
IN
= 6V for T = 10 msec.
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction tem-
perature and the thermal resistance from junction-to-air (i.e. T
A
, T
J
,
θ
JA
).
Time required for V
OUT
to reach 95% of V
R
(output voltage setting), after V
SHDN
is switched from 0 to V
