BD4275FP2-CE2

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The BD4275FP2-CE2 is a low-dropout (LDO) voltage regulator with an integrated voltage detector, manufactured by ROHM Semiconductor. It features a fixed 5 V output and supports up to 500 mA of output current. The device operates within an input voltage range of 5.5 V to 45 V and maintains a typical quiescent current of 65 µA. It provides a typical power supply rejection ratio (PSRR) of 60 dB and exhibits a maximum dropout voltage of 500 mV. The component is housed in a TO-263-5 package and is qualified under the AEC-Q100 standard for automotive applications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrates a voltage detector that outputs a reset signal when the regulated output falls below a specified threshold.
• Features a programmable reset delay time adjustable via an external capacitor connected to the reset pin.
• Includes comprehensive protection mechanisms such as thermal shutdown, over-current protection, and under-voltage lock-out.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• Automotive electronic systems requiring high-voltage tolerance and system monitoring
• Battery-connected circuits needing low standby current consumption
• Microcontroller power supplies with integrated reset functionality

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the current lifecycle status before procurement, as this component may be marked as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors or direct manufacturer channels. Ensure compliance with RoHS directives and functional safety requirements if applicable to your specific automotive or industrial application context.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this regulator for designs requiring a 45 V input tolerance and a fixed 5 V output. It is suitable for applications prioritizing low quiescent current and integrated system supervision. Consider the TO-263-5 package for thermal management and board space constraints. Evaluate the need for external capacitors to program the reset delay time according to system timing requirements.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the BD4275FP2-C series of LDO regulators from ROHM Semiconductor. It is designed specifically for automotive environments, adhering to AEC-Q100 standards. The series focuses on providing reliable power regulation with built-in diagnostic capabilities, making it distinct from standard LDOs that lack integrated voltage detection features.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Check for alternative parts within the BD4275FP2-C family or other ROHM automotive LDOs with similar voltage and current ratings. Verify pin compatibility and electrical specifications before substitution. Note that some variants may have different package options or slightly adjusted performance parameters.
