7A Low Dropout Positive Regualtors
PRODUCTION DATA SHEET
ELECTRICAL CHARACTERISTICS
Unless otherwise specified, the following specifications apply over the operating ambient temperature for the LX8585-xxC / 84A-xxC /
84B-xxC with 0°C ≤ TA ≤ 125°C; VIN – VOUT = 3V; IOUT = 7A. 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.
