BD12IA5MEFJ-ME2

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

The BD12IA5MEFJ-ME2 is a single-output low-dropout linear regulator manufactured by ROHM Semiconductor, designed for automotive applications. 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. Certified under AEC-Q100 standards, it supports a wide operating temperature range from -40°C to +105°C. Key electrical parameters include a line regulation of 25 mV and a load regulation of 25 mV. The unit is housed in an HTSOP-J8 surface-mount package.

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

Verify the specific suffix ME2 against official ROHM documentation to confirm pinout and packaging details. Confirm AEC-Q100 qualification status directly with the manufacturer datasheet. Check for end-of-life or not-recommended-for-new-designations prior to procurement planning. Ensure compatibility with HTSOP-J8 footprint requirements during component sourcing.

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

Select this component when a stable 1.2 V rail is required for automotive-grade logic or sensors. The fixed output eliminates external resistor networks, simplifying design. Consider the 500 mA current limit and 400 mV dropout for headroom calculations. Verify that the 2.5 V minimum input voltage aligns with the system's supply rails under all operating conditions.
