Description

General part information

BD433 Series

The BD433U2EFJ-C is low quiescent regulator featuring 45V absolute maximum voltage,and output voltage accuracy of ±2%(3.3V: Typ.), 200 mA output current and 40μA(Typ.) current consumption. This regulator is therefore ideal for applications requiring a direct connection to the battery and a low current consumption. A logical "HIGH" at the CTL pin enables the device and "LOW" at the CTL pin not enables the device.(Only W: Includes switch) Ceramic capacitors can be used for compensation of the output capacitor phase. Furthermore, This IC also features overcurrent protection to protect the device from damage caused by short-circuiting and an integrated thermal shutdown to protect the device from overheating at overload conditions.This IC uses different production line against series model BD433M2EFJ-C for the purpose of improving production efficiency. We recommend using this IC for your new development. Electric characteristics noted in Datasheet does not differ between Production Line.
