Note B. The above numbers for θJC are maximums for the limiting
thermal resistance of the package in a standard mount-
ing configuration. The θJA numbers are meant to be
guidelines for the thermal performance of the device/pc-
board system. All of the above assume no ambient
airflow.

Note 3. During 60V load dump, VSB shall not be less than 4.75V at IOUT = 10mA.
ELECTRICAL CHARACTERISTICS (Unless otherwise specified, these specifications apply for the operating ambient temperature of
TA = 25°C, VIN = 14V, IO = 500mA for VOUT and 10mA for VSB 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.)
