NOTES: (1) The REG104 does not require a minimum output capacitor for stability. However, transient response can be improved with proper capacitor selection.
(2) Dropout voltage is defined as the input voltage minus the output voltage that produces a 2% change in the output voltage from the value at V
IN
= V
OUT
+ 1V
at fixed load.
(3) Not applicable for V
OUT
less than 2.7V.
(4) Current limit is the output current that produces a 15% change in output voltage from V
IN
= V
OUT
+ 1V and I
OUT
= 10mA.
(5) For V
IN
> 6.5V, see typical characteristic

vs I

.
(6) The REG104 no longer regulates when V
IN
< V
OUT
+ V
DROP (MAX)
. In drop-out or when the input voltage is between 2.7V and 2.1V, the impedance from V
IN
to V
OUT
is typically less than 1Ω at T
J
= +25°C. See typical characteristic
