ABSOLUTE MAXIMUM RATINGS (Note 1)
Pulse (50 ms) Input Voltage from V to V- .......................
IN
50V
Continuous Input Voltage from VIN to V-............................ 40V
Input to Output Voltage Differential................................... 40V
Maximum Output Current ........................................... 250mA

Note 1. Exceeding these ratings could cause damage to the device.
Current from V ..........................................................
REF
25mA
Operating Junction Temperature
Hermetic (T, J, L-Packages)....................................... 150°C
Storage Temperature Range .......................... -65°C to 150°C
Lead Temperature (Soldering, 10 Seconds) ................. 300°C
THERMAL DATA
J Package:
Thermal Resistance-Junction to Case, θJC .................. 30°C/W
Thermal Resistance-Junction to Ambient, θJA .............. 80°C/W
T Package:
Thermal Resistance-Junction to Case, θJC .................. 25°C/W
Thermal Resistance-Junction to Ambient, θJA ........... 130°C/W
L Package:
Thermal Resistance-Junction to Case, θJC .................. 35°C/W
Thermal Resistance-Junction to Ambient, θJA ........... 120°C/W
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 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.
