Description

General part information

BD433S5WFP-C Series

BD433S5WFP-C is low quiescent regulators featuring 45V absolute maximum voltage, and output voltage accuracy of ±2% (3.3V or 5V: Typ), 500mA output current and 38µA (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 enables the device and "LOW" at the CTL disables the device. Ceramic capacitors can be used for compensation of the output capacitor phase. Furthermore, this IC also feature 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 BD433M5WFPJ-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. In addition, the data of BD433M5WFPJ-C is disclosed for documents and design models unless otherwise specified.
