NOTES: (1) The REG103 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 10% change in output voltage from V
IN
= V
OUT
+ 1V and I
OUT
= 10mA.
(5) For V

> 6.5V, see typical characteristic V

.
(6) Logic low indicates out-of-regulation condition by approximately 10%, or thermal shutdown.
(7) The REG103 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
