BD15HA5MEFJ-LBH2

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

The BD15HA5MEFJ-LBH2 is a fixed positive Low Dropout (LDO) regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 1.5V with a maximum output current of 0.5A. 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 includes built-in protection circuits such as over-current protection, thermal shutdown, and a shutdown function that reduces circuit current to 0µA. The regulator supports ceramic output capacitors and is housed in an HTSOP-J8 package.

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

Verify the specific suffix LBH2 against official ROHM documentation to confirm package type and tape/reel specifications. Ensure compatibility with automotive or industrial grade requirements if applicable, as standard variants may differ. Cross-reference the datasheet for exact pinout and thermal characteristics before integration.

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

Select this component when a fixed 1.5V output is required with up to 500mA load capability. Consider the 4.5V minimum input voltage constraint and the 0.6V dropout voltage for headroom calculations. Evaluate the HTSOP-J8 package for thermal management needs and PCB space constraints compared to adjustable variants.
