6A Low Dropout Positive Regulators
PRODUCTION DATA SHEET
ELECTRICAL CHARACTERISTICS
Unless otherwise specified, the following specifications apply over the operating ambient temperature 0°C ≤ TA ≤ 70°C; VIN – VOUT =
3V, IOUT = 6A. 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.
