BD00IA5WEFJ-E2

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

The BD00IA5WEFJ-E2 is a high-accuracy low dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides an adjustable output voltage ranging from 800 mV to 4.5 V with a maximum output current of 500 mA. The device operates within an input voltage range of 2.4 V to 5.5 V and features a typical dropout voltage of 0.4 V at full load. Key electrical specifications include a quiescent current of 250 uA, load regulation of 1.5%, and ripple rejection of 60 dB. The unit is housed in an HTSOP-J8 surface-mount package and supports operation across a temperature range of -25°C to +85°C.

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

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and electrical tolerances. Confirm RoHS compliance status directly with the supplier documentation. Ensure the HTSOP-J8 package footprint matches the design layout. Cross-reference the part number with official ROHM databases to validate availability and production line consistency before finalizing procurement orders.

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

Select this component for applications requiring precise voltage adjustment between 800 mV and 4.5 V with moderate current demands up to 500 mA. The low quiescent current makes it suitable for battery-operated systems where standby power consumption is critical. Consider the thermal dissipation capabilities of the HTSOP-J8 package when designing for high ambient temperatures or continuous full-load operations.

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

This part belongs to the BD00IA5WEFJ series of LDO regulators designed for general-purpose power management. It shares the same physical package and core protection features as other variants in the family but offers unique adjustable output characteristics. The series is positioned for standard-grade consumer electronics applications rather than automotive environments.

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

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other ROHM LDOs only if they share identical pinouts, voltage ranges, and protection features.
