THD at 14.4V power supply.
Features:
D Very Low Number of External Components Required
D Easy Mounting with No Electrical Isolation Between the Package and Heat Sink
D Very Low Transient Noise at Power Switch–On
D No Damage for Reverse Insertion on the PC Board
D Thermal Shut–Down Circuit Included
D Load Dump Protection Circuit Included
Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)
