Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Unless otherwise specified, these specifications apply:
VIN – VOUT = 5V and IOUT = 5A. These specifications are applicable for
power dissipations up to 75W. At input-output voltage differentials greater

than 10V, achievable output current and power dissipation decrease due to
protection circuitry.
Note 3: See thermal regulation specifications for changes in output voltage
due to heating effects. Load and line regulation are measured at a constant
junction temperature by low duty cycle pulse testing.
