NOTES:
1. See thermal regulation specifications for changes in output voltage due to heating effects. Load and line regulation are measured at a constant
junction temperature by low duty cycle pulse testing.
2. Load and line regulation are guaranteed up to the maximum power dissipation (25W for the TCL1584 in “A” pkg., 26.5W for the TCL1585 in
“A” pkg., 18W for the TCL1587 in “A” pkg.). Power dissipation is determined by input/output voltage differential and output current. Guaranteed
maximum output current/power will not be available over full input/output voltage range.
3.
I
FULL LOAD
is defined as the maximum value of output load current as a function of input-to-output voltage. I
FULL LOAD
is a nominal 7A for
TCL1584, decreasing to approximately 3A as V
IN
– V
OUT
increases from 3V to 7V. For all other fixed voltage TCL1585’s, I
FULL LOAD
is 4A. For
the TCL1587, I
FULL LOAD
is 3A. The TCL1585 and 1587 have constant current limit with respect to V
IN
and V
OUT
.
