5A Low Dropout Positive Regulators
PRODUCTION DATA SHEET
ELECTRICAL CHARACTERISTICS
Unless otherwise specified, the following specifications apply over the operating ambient temperature for the LX8384x-xxC with
0°C ≤ TA ≤ 125°C and the LX8384-xxI with -25°C ≤ TA ≤ 125°C except where otherwise noted. Test conditions: VIN -VOUT = 3V;
IOUT = 5A. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient
temperature.
