BD50HC5MEFJ-LBH2

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

The BD50HC5MEFJ-LBH2 is a fixed positive single-output Low Dropout (LDO) regulator manufactured by ROHM Semiconductor. It provides a 1.5A output current with an accuracy of ±1% at 25°C. The device operates within an input voltage range of 4.5V to 8V and delivers a fixed 5V output. It features a typical dropout voltage of 0.6V at full load and includes built-in over-current protection, thermal shutdown, and a shutdown switch that reduces circuit current to 0µA. Designed for industrial applications, it supports ceramic capacitors and utilizes the HTSOP-J8 package.

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

Verify the specific suffix LBH2 to confirm industrial-grade classification and long-time support status. Check RoHS compliance details and ensure the HTSOP-J8 package matches your PCB footprint requirements. Confirm AEC-Q100 qualification if automotive use is considered, though this variant is primarily industrial. Validate datasheet revisions for any updates on recommended replacement parts or design changes.

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

Select this LDO when a fixed 5V output at 1.5A is required with high precision. Consider the 0.6V dropout voltage for headroom calculations between input and output. Ensure the application environment stays within the -40°C to +105°C operating temperature range. Verify that ceramic output capacitors are suitable for the design to leverage the device's stability and longevity benefits.
