CAT431L Datasheet, PDF (3/11 Pages) Catalyst Semiconductor – Low-Voltage Adjustable Precision Voltage Reference

CAT431L
ABSOLUTE MAXIMUM RATINGS
Cathode Voltage .................................................. 18V
REF Current ........................................................ 3mA
Cathode, Anode Currents ............................... 150mA
Operating Junction Temperature ..................... 150°C
Lead Soldering Temperature (10 sec) ............. 260°C
Storage Temperature Range ........... -65°C to +150°C
These are stress ratings only and functional operation is not
implied. Exposure to absolute maximum ratings for prolongued
time periods may affect device reliability. All voltages are with
respect to ground.
ELECTRICAL CHARACTERISTICS
Electrical characteristics are guaranteed over the full operating temperature range of -40°C to +85°C with a junction
temperature from -40°C to +105°C unless otherwise specified. Ambient temperature must be de-rated based upon
power dissipation and package thermal characteristics.¹
