Test Conditions

Parameter

Note 4. 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

MAX for K, R, and IG packages is VIN - VOUT = 3V / 1.5A and VIN - VOUT = 40V / 240mA. For T and L packages IMAX is V IN - VOUT = 3V / 500mA

and V

IN

- V

OUT

= 40V / 150mA.
