ELECTRICAL CHARACTERISTICS
Unless otherwise specified, the following specifications apply over the operating ambient temperature for the LX8587x-xx with
0°C ≤ T_A ≤ 125°C. Test conditions: V_IN -V_OUT = 3V; I_OUT = 3A. Low duty cycle pulse testing techniques are used which maintains
junction and case temperatures equal to the ambient temperature.
