BD12IC0MEFJ-ME2

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

The BD12IC0MEFJ-ME2 is a single-output low-dropout (LDO) linear voltage regulator manufactured by ROHM Semiconductor. It provides a fixed 1.2 V output with a maximum current capacity of 500 mA. The device operates within an input voltage range supporting up to 5.5 V and maintains regulation across a junction temperature range from -40 °C to +105 °C. Key electrical specifications include a typical dropout voltage of 400 mV at full load, line regulation of 25 mV, and load regulation of 25 mV. The unit features a quiescent current of 500 uA and 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 that the component meets AEC-Q100 grade requirements if used in automotive environments. Check for end-of-life status as some variants in this series are marked NRND. Ensure compatibility with HTSOP-J8 footprint during PCB layout verification.

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

Select this regulator when a fixed 1.2 V supply is required with moderate current demands up to 500 mA. Consider the 400 mV dropout voltage relative to your minimum input voltage headroom. Evaluate the thermal performance given the 2.11 W power dissipation capability in the HTSOP-J8 package. Verify that the 500 uA quiescent current aligns with system standby power constraints.
