BD00EA5WFP-E2

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

The BD00EA5WFP-E2 is a positive, adjustable output Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It operates within an input voltage range of 3 V to 42 V and delivers a maximum output current of 500 mA. The device supports an adjustable output voltage range from 1.2 V to 16 V with a typical reference voltage of 650 mV. Key electrical specifications include a typical dropout voltage of 450 mV at full load, a ripple rejection ratio of 70 dB, and a quiescent current of 17 uA. Voltage regulation accuracy is specified at ±1% at 25°C. The component is housed in a TO-252-5 surface-mount package and is rated for operation between -40°C and +105°C.

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

Verify the complete part number including the suffix E2 to ensure compliance with specific manufacturing standards and environmental regulations. Confirm that the required output voltage setting aligns with the resistor network design, as the internal reference is fixed. Ensure the application environment remains within the specified -40°C to +105°C operating temperature range to maintain guaranteed performance parameters.

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

Select this component when a high input voltage tolerance up to 42 V is required alongside moderate current delivery. The adjustable output feature provides flexibility for various voltage rails compared to fixed-output alternatives. Consider the TO-252-5 package for adequate thermal dissipation during continuous 500 mA operation. Evaluate the 17 uA quiescent current against system power budgets for battery-operated designs.

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

This device belongs to the BD00EA5WFP series of high-voltage LDO regulators from ROHM Semiconductor. The series is characterized by its ability to handle significant input voltage differentials while maintaining stable output regulation. The E2 suffix typically denotes specific packaging or environmental compliance variations within the manufacturer's product line, distinguishing it from earlier revisions or alternative package options.

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

Direct substitutes may include other ROHM LDOs with similar 42 V input ratings and adjustable outputs, such as the BD00EA5WFP without the E2 suffix if package compatibility allows. Cross-manufacturer replacements must match the 500 mA current capacity, TO-252-5 footprint, and adjustable voltage range. Verify pinout compatibility and thermal characteristics before substitution.
