BD25HA5MEFJ-ME2

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

The BD25HA5MEFJ-ME2 is a single-output positive fixed low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 2.5 V output with a maximum current capacity of 500 mA. The device operates within an input voltage range of 4.5 V to 8 V and features a typical dropout voltage of 600 mV at full load, with a maximum of 900 mV. It is housed in an HTSOP-J8 surface-mount package and supports an operating temperature range from -40°C to +105°C. The component holds AEC-Q100 qualification for automotive applications.

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 compliance requirements for your target application. Check for end-of-life status as some variants in this series are marked NRND. Ensure input voltage stays within the 4.5 V to 8 V limit to maintain regulation.

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

Select this component when a fixed 2.5 V rail is required with up to 500 mA load capability. The HTSOP-J8 package suits space-constrained surface-mount designs. Consider the 600 mV typical dropout when designing for minimum input voltage margins. Verify thermal dissipation capabilities given the 2.11 W power dissipation rating in the specified package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the BD25HA5MEFJ series of high-accuracy LDO regulators designed for automotive use. It shares the same functional block and protection features with other output voltage variants in the family, such as BD25HA3MEFJ-ME2 or BD70HA5MEFJ-ME2, differing primarily in the fixed output voltage setting.
