Parameters Sym Min Typ Max Units Conditions
Note 1: The minimum V
IN
must meet two conditions: V
IN
2.0V and V
IN
(V
R
+ 1.0V).
2: 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
temperature range. V
OUT-LOW
= lowest voltage measured over the temperature range.
4: 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
.
5: 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.
