BD30IA5MEFJ-ME2

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

The BD30IA5MEFJ-ME2 is a single-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed 3.0 V output with a maximum load current of 0.5 A. The device operates within an input voltage range of 2.4 V to 5.5 V and features a typical dropout voltage of 0.4 V at full load. It includes integrated protection circuits for overcurrent, thermal shutdown, and a shutdown function that reduces standby current to 0 µA. The component is housed in an HTSOP-J8 package and is qualified under the AEC-Q100 standard for automotive reliability.
