500-mA 3.3-V or 5.0-V Output LDO Regulators
BD4xxM5-C Series
●General Description
●Features
The BD4xxM5 series are low quiescent regulators featuring 45 V absolute maximum voltage, and output voltage accuracy of ±2 % (3.3 V or 5 V: Typ.), 500 mA output current and 38 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 enables the device and “LOW” at the CTL disables the device. (Only W: Includes Enable Input). 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.
