200mA 3.3V or 5.0V Output LDO Regulators - BD450M2EFJ-C

The BD4xxM2-C series are low quiescent regulators featuring 45 V absolute maximum voltage, and output voltage accuracy of ±2 % ( 3.3 V or 5.0 V: Typ.), 200 mA output current and 40 µA (Typ.) current consumption. These regulators are 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, these ICs 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.
