Note B. The above numbers for

JC are maximums for the limiting

thermal resistance of the package in a standard mount-

ing configuration. The

JA numbers are meant to be

guidelines for the thermal performance of the device/pc-

board system. All of the above assume no ambient

airflow.

ELECTRICAL CHARACTERISTICS

(Unless otherwise specified, these specifications apply for the operating ambient temperature of

= 25°C. V

= 14V. I

= 500mA for V

OUT

and 10mA for V

and are for DC characteristics only. Low duty cycle pulse testing techniques are

used which maintains junction and case temperatures equal to the ambient temperature.)
