NCV8612B Datasheet, PDF (5/26 Pages) ON Semiconductor – Ultra-Low Iq Automotive System Power Supply IC Power Saving Triple-Output Linear Regulator

NCV8612B
SUPPLY VOLTAGES AND SYSTEM SPECIFICATION ELECTRICAL CHARACTERISTICS (7 V < ASO_RAIL < 18 V, VIN−H
= VIN−B w ASO_RAIL, V_PP = 5 V, VIN_S3 tied to ASO_RAIL, VBATT_MON = 0 V, EN = 5 V, IGNIN = 0 V, I_SYS = 3 mA (Note 6))
Minimum/Maximum values are valid for the temperature range −40°C v T_J v 150°C unless noted otherwise. Min/Max values are
guaranteed by test, design or statistical correlation.
