BD80GA5WEFJ-E2

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

The BD80GA5WEFJ-E2 is a high-accuracy linear low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed positive output voltage of 8.0 V with a maximum continuous output current capability of 500 mA. The device operates within an input voltage range from 4.5 V to 14 V and maintains stable performance across a junction temperature range of -25°C to +85°C. Key electrical specifications include a quiescent operating current of 600 µA, a load regulation of 1.5%, and a maximum power dissipation rating of 2.11 W. The component is housed in an HTSOP-J8 surface-mount package.

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

Verify the complete part number including the suffix to confirm specific tape-and-reel packaging configurations and RoHS compliance status. Ensure that the ordering documentation explicitly references the E2 designation to match the intended manufacturing revision. Cross-reference the datasheet version against the supplier's provided specification sheet to confirm accuracy of the electrical parameters before finalizing procurement orders.

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

Select this component when a fixed 8.0 V output is required with moderate current demands up to 500 mA. Consider the 4.5 V minimum input voltage constraint relative to the source supply rail. Evaluate the thermal performance based on the 2.11 W power dissipation limit and the ambient operating temperature range. Compare against adjustable variants if flexible output voltage settings are necessary for the design.

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

This regulator belongs to the BDxxGA5WEFJ series of high-accuracy LDO regulators from ROHM Semiconductor. The family shares common package dimensions and basic functional architectures while varying in fixed output voltage levels. Similar members include the BD50GA5WEFJ-E2 for 5.0 V outputs and the BD80FC0WEFJ-E2 for higher current applications. The series targets cost-sensitive applications requiring reliable linear regulation without external feedback components.

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

Direct pin-compatible substitutes within the same series include BD50GA5WEFJ-E2 and BDJ2GA5WEFJ-E2, though these offer different fixed output voltages. Verify that any alternative component matches the 500 mA output current requirement and the 14 V maximum input voltage limit. Ensure the replacement supports the HTSOP-J8 package footprint and meets the -25°C to +85°C operating temperature range.
