ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over the operating ambient temperatures for the LX8382/8382A-xxC with 0°C ≤ TA ≤ 125°C;
VIN - VOUT = 3V; IOUT = 10A. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient
temperature.)

Note 2. Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to
heating effects are covered under the specification for thermal regulation.
Note 3. These parameters, although guaranteed, are not tested in production.
Note 4. See Maximum Output Current Section above.
