BD4x Automotive/Industrial LDO Voltage Regulators

ROHM Semiconductor BD4x Automotive/Industrial LDO Voltage Regulators are low quiescent regulators featuring 45V absolute maximum voltage. These regulators offer an output voltage accuracy of ±2% (3.3V or 5.0V typ.). The BD4x regulators from ROHM Semiconductor are ideal for applications requiring a direct connection to the battery and low current consumption.
