ELECTRICAL CHARACTERISTICS (continued)

(7 V < ASO_RAIL < 18 V, VIN−H = VIN−B w ASO_RAIL, VPP = 5 V, VIN_S3 tied to ASO_RAIL, VBATT_MON = 0 V, EN = 5 V,

IGNIN = 0 V, ISYS = 3 mA (Note 6)) Min/Max values are valid for the temperature range −40°C vTJ v 150 °C unless noted otherwise.

Min/Max values are guaranteed by test, design or statistical correlation.

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

7. Dropout voltage is measured when the output voltage has dropped 100 mV relative to the nominal value obtained with ASO_RAIL = VIN_S3

= 13.2 V.

8. Not tested in production. Limits are guaranteed by design.

9. Refer to CIRCUIT DESCRIPTION Section for Stability Consideration

10. For other voltage versions refer to Typical Performance Characteristics Section.
