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.

The minimum V
IN
must meet two conditions: V
IN
≥
2.0V and V
IN
≥
(V
R
+ 1.0V).
V
R
is the nominal regulator output voltage. For example: V
R
= 1.8V, 2.5V, 3.0V, 3.3V, or 5.0V.
The input voltage V
IN
= V
R
+ 1.0V or Vi
IN
= 2.0V (whichever is greater); I
OUT
= 100 μA.

Temperature), V
OUT-HIGH
= highest voltage measured over the tem-
perature range. V
OUT-LOW
= lowest voltage measured over the temperature range.
Load regulation is measured at a constant junction temperature using low duty cycle pulse testing. Changes in output
voltage due to heating effects are determined using thermal regulation specification TCV
OUT
.
Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its measured
value with an applied input voltage of V
R
+ 1.0V or 2.0V, whichever is greater.
