is set by external resistor divider to 5 V.
12. V

for other fixed voltage versions, as well as adjustable versions set to other output voltages, can be calculated from the following formula:
V

* V

n(x)
is the typical value from the table above.
13. Performance guaranteed over specified operating conditions by design, guard banded test limits, and/or characterization, production tested
at T
J

A
= 25C. Low duty cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as
possible.
