BD3925FP-C
500mA, Low Iq Voltage Tracker for Automotive

This IC is voltage trackers for automotive use which feature high withstand-voltage to 50V. They offer the output current loading to 500mA while limiting the quiescent current to 45µA(typ), so that they suit to apply for systems which are permanently connected to the car battery and requiring low-current-consumption. The offset is±15mV(for 5V output.6V
