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
+ 1V at fixed load.
(3) Not applicable for V
less than 2.7V. (4) Current limit is the output current that produces a 10% change in output voltage from V
= V
+ 1V and I
= 10mA.
(4) For V
> 6.5V, see typical characteristic “V
vs I
ENABLE
.” (6) Logic low indicates out-of-regulation condition by approximately 10%, or thermal shutdown. (7) The
REG103 no longer regulates when V
< V
+ V

OUT
