BD30HC5MEFJ-LBH2

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

The BD30HC5MEFJ-LBH2 is a fixed-output Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor, designed for industrial applications. It delivers a maximum output current of 1.5A with a fixed output voltage accuracy of ±1% at 25°C. The device operates within an input voltage range of 4.5V to 8V and features a typical dropout voltage of 0.6V at full load. It utilizes the HTSOP-J8 surface-mount package and supports operation across a temperature range from -40°C to +105°C. Key electrical characteristics include a circuit current of 0.6mA, ripple rejection of 60dB, and load regulation of 25mV. The regulator includes built-in protection circuits such as over-current protection and thermal shutdown.

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

Verify that the specific suffix LBH2 corresponds to the industrial-grade long-term support variant rather than standard automotive or consumer grades. Confirm RoHS compliance status and ensure the HTSOP-J8 package dimensions match the target PCB footprint. Check for any recent product change notices regarding pinout or electrical parameter updates before finalizing procurement orders.

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

Select this component when a fixed 1.5A output with ±1% accuracy is required in an industrial environment. Ensure the input voltage remains within the 4.5V to 8V window to maintain proper regulation. Consider the thermal dissipation capabilities of the HTSOP-J8 package if operating near maximum current limits. Verify compatibility with ceramic output capacitors as specified in the datasheet to ensure stability without additional external components.
