(Unless otherwise specified, these specifications apply over the operating ambient temperatures for the LX8386/86A/86B-xxC with 0°C
and the LX8386-xxI with -25°C
and case temperatures equal to the ambient temperature.)

LX8386/86A/86B-33 (3.3V Fixed)
Note 2. Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to
Note 3. These parameters, although guaranteed, are not tested in production.
Note 4. See Maximum Output Current Section above.
