BD12IA5VEFJ-ME2

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

The BD12IA5VEFJ-ME2 is a single-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 1.2 V with a maximum output current of 500 mA. The device operates within an input voltage range of 2.5 V to 5.5 V and features a typical dropout voltage of 400 mV at full load, with a maximum of 600 mV. It is housed in an HTSOP-J8 surface-mount package and supports an operating temperature range from -40°C to +105°C. The regulator includes protection features such as thermal shutdown and overcurrent protection.

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

Verify the exact suffix ME2 against the manufacturer's latest datasheet to confirm pinout and electrical specifications match your design requirements. Confirm RoHS compliance status and AEC-Q100 qualification level directly with ROHM or authorized distributors before finalizing procurement. Ensure the HTSOP-J8 footprint matches your PCB layout guidelines.

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

Select this component when a fixed 1.2 V rail is required for automotive-grade applications with moderate current demands up to 500 mA. Consider the 400 mV typical dropout voltage relative to your minimum input supply. Verify that the HTSOP-J8 package dimensions fit your assembly constraints and that the -40°C to +105°C temperature range covers your operational environment.
