BD10IA5JEFJ-E2

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

The BD10IA5JEFJ-E2 is a fixed-output linear low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable positive output of 1.0 V with a maximum load current capability 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 400 mV at full load. Quiescent current is specified at 5 uA, contributing to efficient power management in battery-operated systems. It is housed in an 8-pin HTSOP-J package with an exposed pad for thermal dissipation.

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

Verify the complete part number including suffixes such as -E2 against official ROHM documentation to ensure correct packaging and compliance status. Confirm that the supplier source provides genuine components with traceable lot codes. Check RoHS compliance details directly from the manufacturer datasheet rather than relying solely on distributor summaries. Ensure the ordering quantity matches the required reel or cut-tape specifications for your assembly process.

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

Select this component when a fixed 1.0 V output is required with moderate current demands. Compare its 5 uA quiescent current against other LDOs if battery life is critical. Verify that the input voltage remains within the 2.4 V to 5.5 V range under all operating conditions. Consider the thermal performance of the HTSOP-J package if high ambient temperatures or continuous full-load operation is expected.

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