Note A. Junction Temperature Calculation: TJ = TA + (PD x θJA).
Note B. The above numbers for
θJC are maximums for the limiting
thermal resistance of the package in a standard mounting configuration. The θ
JA
numbers are meant to be
guidelines for the thermal performance of the device/pcboard system. All of the above assume no ambient
airflow.

ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply for the operating ambient temperature of TA = 25°C, VIN = VC = 12V, V- = 0V, V
OUT
= 5V, IL =
1 mA, R
SC
= 0Ω, C1 = 100pF, and divider impedance as seen by error amplifier ≤ 10KΩ. Low duty cycle pulse testing echniques are used which maintains
junction and case temperatures equeal to the ambient temperature.)

Note 4. These parameters, although guaranteed,
are not tested in production.
Note 3. Applies for constant junction temperature. Temperature drift effects must be taken
into account separately when the unit is operating under conditions of high dissipation.
