Test Conditions
Parameter
Note4. Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating
effects are covered under the specification for thermal regulation.
Note 5. These parameters, although guaranteed, are not tested in production.
Note 6. I
for K, R, and IG packages is V
IN
- V
OUT
= 3V / 1.5A and V
IN
- V
OUT
= 40V / 240mA. For T and L packages I
MAX
is V
IN
- V
OUT
= 3V / 500mA
and V
IN
- V
OUT
= 40V / 150mA.
