BD50HA3MEFJ-LBH2

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

The BD50HA3MEFJ-LBH2 is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 5 V output with a maximum current capacity of 300 mA. The device operates within an input voltage range of 4.5 V to 8 V and maintains a typical dropout voltage of 600 mV. Designed for automotive applications, it features high accuracy and includes built-in protection mechanisms such as over-current protection and thermal shutdown. The component is housed in an HTSOP-J8 package and supports surface-mount installation.

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

Verify the specific suffix ME2 against the requested model, as the provided documentation lists BD50HA3VEFJ-ME2 rather than BD50HA3MEFJ-LBH2. Confirm RoHS compliance status and ensure the HTSOP-J8 package matches your PCB footprint requirements. Check for AEC-Q100 qualification if automotive grade certification is mandatory for your design.

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

Select this regulator when a precise 5 V supply is needed for automotive-grade components with moderate current demands. Ensure the input voltage remains within the 4.5 V to 8 V window to maintain regulation. Consider the thermal performance in your enclosure design, as the device dissipates heat proportional to the voltage difference between input and output multiplied by the load current.
